The wavelength is approximately perpendicularly coupled and excited after the convergence to produce a laser phenomenon, or the reflective layer will penetrate the solar silicon wafer and diffract the pump wavelength, which is not fully utilized, into the optical gain medium again to achieve the function of the amplifier. [Previous technology] According to the current, erbium-doped fiber amplifiers generally excite erbium-doped fiber with an output wavelength of 980 nm at a milliwatt of about 10 meters to obtain about 20-30 in the range of 1530 mn to 1560 ⑽.仳 's optical amplification gain; however, driving this semiconductor laser and its cooling chip for temperature control needs to continuously consume about 1 amp of current. It is expected that with the pump of 148G nm, the length will consume more power. Where special energy sources such as satellite 'alpine', north and south poles have difficulty in obtaining electrical energy, it will cause bottlenecks in optical communication applications. And the use of solar power, because T will cause damage to the earth's resources and ecological environment, so in various countries at present, Asia is respected and committed to development. Similarly, 'the way of focusing sunlight using reflection or refraction to excite the optical gain medium to achieve field emission with energy as high as tens of watts' has been successfully experimented for decades and has become the goal of continuous efforts by scientists, but In the past, almost all of the previous methods used 200531299 to make use of large focusing lenses to collect enough sunlight wavelengths to obtain large gains. Such a structure makes the solar Golpo laser or optical amplification H only become a research carried out by a few scientists in the laboratory and cannot be widely applied to commercial products, so let alone put such a huge device on an artificial satellite or the International Space Station It's over. However, in response to the needs of meteorological or military satellites to transmit large amounts of data or image data in a short period of time, satellite optical communicators are committed to the development of key projects, such as between the satellite and the satellite = high-speed between the ground and the ground station Data transmission, wireless optical communication is undoubtedly the best choice. In addition, the high directivity of laser light also provides a high degree of communication security and security; and satellite optical communication is also a key national development project of various countries around the world. Therefore, it is necessary to implement wireless light on satellites. A small-sized solar energy amplifier with conversion efficiency has undoubtedly become one of the necessary important equipment. What about the η of lasers with general gain and high output power (up to 18W)? This is achieved by means of solar pumping. However, it can be found that the beam focusing method of /, China Pacific = light is almost always achieved by using a large parabolic mirror or focusing method using non-shirt-like optics, and the volume of the entire experimental structure is also very large, so it is practical. Sex is not very high. Furthermore, 'all sunlight is focused as much as possible into the human optical gain medium. The medium must be cooled with cooling water at the same time to avoid the situation of excessive heating of the crystal. LL and its small size have wavelength-selective characteristics ..., The key factor is whether the solar optical amplifier and laser 200531299 can be successfully used in the future; and: the conventional technology is added to the structure of the holographic grating in the optical waveguide t, which can make the energy transmitted in the optical waveguide It is almost perpendicularly coupled to emit the optical waveguide and produce a focusing effect like Fresnel Lens. According to the principle of reversible optical path, if the parallel beam perpendicular to this waveguide grating is turned into the optical waveguide, A grating called holographic antenna grating, which occurs at the focal point, has a diffraction efficiency of about 40% at a specific wavelength and can be simply added with a reflective layer under the grating to make the moon . The pump light is used to re-reflect the diffraction grating to increase the diffraction efficiency. However, the use of these gratings is limited to coupling the signal light in the optical waveguide to the optical waveguide or coupling the external signal light into the optical waveguide for transmission. It has not been proposed to make a large-area holographic antenna grating as a specific one in sunlight. Wavelength collectors and couple them to optical gain media to generate lasers; 'At present, holographic antenna gratings are used to couple external pump light into the optical waveguides with optical gain media underneath in a nearly vertical manner for transmission. Make an optical amplifier. However, it does not propose a coupling device for making a large area of a specific wavelength of sunlight, and it does not propose to make a circular holographic grating to make the pump wavelength converge to the center of the grating to concentrate a large amount of energy to excite the light. The gain medium enables laser and light amplification effects. Furthermore, their method of gaining optical signal gain is achieved by using the evanescent field. Therefore, the excitation effect is not 200531299. As we proposed, the pump light is directly coupled into a high-concentration erbium-doped waveguide to make the signal light, The way the pump light and the optical gain medium strongly overlap is so efficient. [Summary of the Invention] Therefore, the main object of the present invention is that the pump wavelength required in sunlight can be approximately vertically coupled to the horizontal direction and transmitted to the The direction of the wave guides converges to receive the excitation of the pump wavelength to produce a laser phenomenon. Another object of the present invention is to greatly improve the diffraction efficiency at a vertical angle, and to diffract the pump wavelength that has not been properly utilized through the solar silicon wafer plate into the optical gain medium through the reflective layer. Achieve the function of the amplifier, and improve the diffraction efficiency. Another object of the present invention is to use a solar pumped optical amplifier without electricity, and is suitable for special environments such as artificial satellites, international space stations, alien planet exploration bases, national kidney long-distance route aircraft, mountains, deserts, north and south poles, etc. When used with a spare solar battery, it can also be used as an energy-saving optical communication signal amplification device, but if it is used on the ground, it may be more suitable for use in dry or dry climate areas such as continental or desert (except during sandstorm season). 'And suitable for use at the top of the corporate building. Another object of the present invention is to solve the power demand problem of current optical communication amplifiers. In order to achieve the above object, the present invention is a solar light active element, which is provided with a holographic antenna grating on a solar cell wafer plate. 200531299 and a waveguide is provided at the center of the holographic antenna grating. With the holographic antenna grating, the pumping wavelength required in sunlight is approximately vertical and horizontally transmitted to the horizontal direction and converges to the direction of the waveguide to receive the excitation of the Kuripu wavelength, which can greatly improve the vertical angle of the wavelength. Radiation efficiency: A light gain medium is set at the center of the waveguide, and there is a -layer reflective layer on the solar stone wafer plate. The reflective layer can penetrate the holographic antenna grating and fail Make good use of the pump wavelength to reflect and diffract into the optical gain medium again to improve the total diffraction efficiency; so that the invention can solve the current power demand problem of optical communication application optical amplifiers, without the need to use solar pumped light Amplifier, suitable for special environments such as artificial satellites, international satellite stations, alien planet exploration bases, international long-distance route aircraft, mountain deserts, north and south poles, etc. It can also be used as an energy-saving optical communication signal amplification device when the pool is used. However, if the sundial is used on the ground, it may be more suitable for use in dry or rainy climate areas such as continental or desert (except during sandstorm season), and suitable for installation.

In other words, the present invention can be applied to any place where the solar wafer sheet 1 (solar cell) is used. The above-mentioned holographic antenna grating with wavelength selection characteristics can realize the coupling of the pump wavelength in the almost normal incident sunlight spectrum into a pump wavelength that travels in the horizontal direction. This has the advantage of using solar silicon wafers1 The waveguide layer 2 above, couples the 98 ° or 1480 nm wavelength of sunlight into the waveguide layer 丄 2 in a vertical manner, and gathers the center of the hologram antenna grating 2 1 into the erbium-doped waveguide 3 to excite Krypton ions achieve the effect of 15 200531299 of optical amplification at a wavelength of 1530nm to 1560nm. If further combined with a laser light reflection grating, a laser phenomenon can be generated. Among them, this wavelength selects the omnidirectional antenna grating 2 to diffract the wavelength of 98Onm or 1480nm into the waveguide 3, and will not affect the main light absorption band (550nm-75Onm) of solar silicon wafer 1 (solar cell) battery power generation. Therefore, the advantage of such a structure is that only a waveguide layer 12 is mined on the original large-area 1% NEM wafer chip 1 and a large-area holographic antenna grating 2 is formed thereon. To achieve the purpose of optical communication without affecting the solar silicon wafer 1 (solar cell) power generation; however, the fatal disadvantage of holographic antenna grating 2 is that its theoretical limit of diffraction efficiency is only 40%, in other words, the sun The highest wavelength of 98nm in the light is only waveguide 3 which can be transmitted horizontally by Ima and enters the center, and the remaining 60% will penetrate the solar silicon wafer panel i (solar cell) below. However, later calculations can verify that even if the diffraction efficiency is only 30%, a square diffraction plate with an area of 30cm * 30cm can still generate a pump energy greater than 20Dmw. As for the diffraction efficiency, It is possible to simply use the additional reflective layer 5 below the holographic antenna grating 2 to reflect back to the holographic antenna the pump wavelength that has penetrated the dioxide cutting waveguide layer 12 and failed to make good use of it. The grating 2 is converted to the skin-guiding layer 12 and conducted in the optical gain medium 4 to achieve the function of the amplifier /, thereby effectively improving the diffraction efficiency of the holographic antenna grating 2 indirectly. Please refer to "Figure 5", which is not intended for the serial connection of the amplifier of the present invention; wherein the solar light active element can be input to the terminal phase through the output end and another 200531299 device in series. The connection achieves the amplification result, thereby acting as an amplifier. It is guessed as shown in Fig. 6 ", the string of solar light active components of the laser of the present invention can achieve the effect of laser cascading by connecting the output terminal and the input terminal of the other laser device. Refer to the "Figure 7, δ chart", which is the absorption spectrum of the measuring glass of the present invention, the spectrum of the 98Gnm laser diode measured by the present invention. "As shown in the figure: It is measured by the US Navy Laboratory For simple estimation of the frequency of solar light (Appendix 1). · According to the annex, the total solar energy per square meter measured by the US Navy ’s laboratory on the ground is 1366 w / n] 2. The 旎 1 at Qing 旎 is about 887.5 mw / nm · m2, and we consider that the waveguide 3 (that is, doped with glass) can be excited in the sun. The wavelength is only 97nm-980nm (such as the seventh As shown in the figure), in fact, 965_985 can be approximately vertically coupled to the waveguide layer i 2, so the effective pump wavelength energy we can obtain from sunlight is 887.5 mw / nm · m2 χ (985-975 ) = 8875 mw / m2 = 8875 χ ΙΟ 4 mw / cm2 ° 2. Consider using a square holographic antenna grating with an area of 30cm * 3〇Cm 2 'then The total energy of the pump wavelength received by Taiguang is 8 8 ω 5 χ 1 〇 -4 mw / cm2 χ 30cm χ 30cm = 789 · 75 mw. 3. The theoretical diffraction limit of the holographic antenna grating 2 is 4, if we only obtain 30% diffraction efficiency in 200531299, the total energy of the pump wavelength received is 789.75 X 0.3 = 236.925 mw; heart cord 3〇 The holographic antenna grating 2 of cmx3〇Cm can obtain a pumping energy of 980nm greater than 2000mw, and it is pure energy near 980nm. However, the area of the solar panel on the satellite is several meters x several meters. Therefore, the feasibility of the amplifier of the present invention can be proved.

效於一顆280mw之980nm半導體雷射；且第9、1〇圖 中’摻餌光纖放大器的自發放大輻射（ASE)功率看起 來似乎很弱，原因是一方面波導管3 (即摻餌玻璃）輸 出的摻铒光纖放大器的自發放大輻射（ASE)能量沒有聚 焦進入光譜分析儀，另，泵浦波長未能全面地將體積這 麼大一塊的波導管3 (即摻餌玻璃）完全激發也是—個 原因，但這些並不影響相同條件下的比較結果，第9圖 的1. 53μηι波義的增益似乎比第丄〇圖小多了，這其實是 因為函素燈導入較多的白光進入光譜分析儀，導致雜2 位準（noise 4〜1)上升所致。此處，我們只關心摻铒光 纖放大器的自發放大輻射（ASE)的輸出能量到底能達到 何種程度’這是攸關光源的泵浦能力，若將鹵素燈的其 他波長濾掉，第9圖的增益也可跟第1 〇圖一樣高。再 者，我們亦可推測每平方公尺的太陽能量為i 36kw卢 19 200531299 右，倘使全像天線光柵2的繞射效率僅有30 %，我們仍 可得到450W左右的總能量，還是比250W的鹵素燈泡能 量強，因此，大約只要一塊50cm*50cm見方的全像繞射 板，就可以成功地達到如同280mw的980nm栗浦雷射之 功效。 請參閱『第1 1、1 2圖』所示，係本發明利用 30cm*30cm的Fresnel聚焦板將太陽光聚焦到波導管上 量得之增益頻譜圖、本發明調整980nm雷射的電流以模 # 擬第11圖之太陽光強度圖。 如圖所示，以下是實際利用太陽光聚焦激發波導管 3 (即摻斜玻璃）方式的結果並與10 Omw的98 Onm泵浦 雷射激發波導管3 (即摻铒玻璃）之結果做比較： 1. 於中午多雲時晴天氣，氣溫攝氏30度，利用一片 30cm*30cm的壓克力材質之全像菲涅爾透鏡（Fresnel lens)聚焦板將太陽光側向聚焦於上述之波導管3(即 摻铒玻璃）上，並利用光譜分析儀量測此波導管3 (即 · 摻铒玻璃Γ的光放大效果（受激與自發輻射未使用聚 焦透鏡直接量測），得到第1 1圖的光增益頻譜， 1.54 μπι波長能量可以達-40 dBm左右，其中1·4μπι 微米附近的凹陷是因為壓克力材質本身的能帶吸收所 致。 2. 利用980nm泵浦雷射操作在206 mA的電流下，經由光 功率計（power-meter)量測得到100 mw的能量，將此 20 200531299 能量利用侧向激發方式及相同實驗條件下，激發波導 管3 (即摻铒玻璃），得到第1 2圖之增益頻譜，其中 1.53 nm處的摻铒光纖放大器的自發放大輻射（ase) 能量為-42 dBm左右。 由第1 1圖及第1 2圖比較，我們發現一片 30cm*30cm的Fresnel聚焦板激發波導管3 (即摻铒玻 璃）的能力至少大於1〇〇歸的98〇nm泵浦雷射，況且， 太陽光聚焦到波導管3 (即摻铒玻璃）上時，因為光束 較大，所以並非所有的能量都進入波導管3 (即摻餌玻 璃）；反觀980 nm泵浦雷射，因為是從光纖輸出，所以 可以把很強的能量集中輸出在較小的區域上使波導管3 (即摻餌玻璃）得到較高的粒子居量反轉。 一故利用太陽光聚焦的方式，可以很輕易地就達到平 常高功率980 rnn泵浦雷射的激發功效，因此，一但普及 推廣太陽能光放大器，應當可以對光通訊（尤指衛星光通 Λ及地面無線光通訊）產生重大的技術改革。 惟以上所述者，僅為本發明之較佳實施例而已，當 不能=此限定本發明實施之範圍；故，凡依本發明申請 專利範圍及發明說明書内容所作之簡單的等效變化與修 飾，皆應仍屬本發明專利涵蓋之範圍内。 ^ 21 200531299 【圖式簡單說明】 第1圖’係本發明之放Ail運作原理上視示意圖。 第2圖，係本發明之放大器側視圖。 第3圖，係本發明之放大器戴面示意圖。 第4圖，係本發明之雷射運作原理上視示意圖。 第5圖，係本發明之放大器之串接示意圖。 第6圖，係本發明之雷射之串接示意圖。 第7圖，係本發明量測摻铒玻璃之吸收頻譜圖。 第8圖，係本發明量測98Qnm雷射二極體之頻譜圖。籲 第9圖，係本發明以250W鹵素燈泡照射波導管量得之增 益頻譜圖。 第1 0圖，係本發明以280mW的980雷射照射波導管得 到之增益頻譜圖。 第1 1圖，係本發明利用30cm*30cm的Fresnel聚焦板 將太陽光聚焦到波導管上量得之增益頻譜圖。 第1 2圖’係本發明調整980nm雷射的電流以模擬第9 _ 圖之太暢光強度圖。 附件一：美國海軍實驗室所量測的太陽光頻譜。 【元件標號對照】 太陽能矽晶片板1 光學繞射元件21 第一光學反射元件2 2 第二光學反射元件2 3 波導管3 光增益介質4 反射層5 抗反射膜1 1 22 200531299 波導層1 2 輸入端6 1 輸出端6 2 輸入端7 1 輸出端7 2It is effective for a 280mw 980nm semiconductor laser; and the spontaneous amplified radiation (ASE) power of the 'bait-doped fiber amplifier in Figures 9 and 10 appears to be weak, because the waveguide 3 (ie bait-doped glass) The spontaneous amplified radiation (ASE) energy of the erbium-doped fiber amplifier output is not focused into the spectrum analyzer. In addition, the pump wavelength fails to fully excite the waveguide 3 (ie bait-doped glass) of such a large volume— There are several reasons, but these do not affect the comparison results under the same conditions. The gain of 1.53μηι in Figure 9 is much smaller than that in Figure 丄 0. This is actually because the white light is introduced into the spectrum by the function lamp. The analyzer is caused by the rise of the noise level 2 (noise 4 ~ 1). Here, we are only concerned with the extent to which the output energy of spontaneous amplified radiation (ASE) of an erbium-doped fiber amplifier can be reached. This is the pumping ability of the light source. If other wavelengths of the halogen lamp are filtered out, Figure 9 The gain can also be as high as in Figure 10. In addition, we can also speculate that the amount of solar energy per square meter is i 36kw Lu 19 200531299 right. If the diffraction efficiency of the holographic antenna grating 2 is only 30%, we can still obtain a total energy of about 450W, which is still better than 250W. The halogen light bulb has strong energy. Therefore, only a 50cm * 50cm square holographic diffraction plate can successfully achieve the effect of 980nm Lipu laser as 280mw. Please refer to the "Figures 1 and 12", which is a gain spectrum spectrum measured by the present invention using a 30cm * 30cm Fresnel focusing plate to focus sunlight on a waveguide, and the present invention adjusts the current of a 980nm laser to modulate # The sun light intensity map of the eleventh figure. As shown in the figure, the following is the actual result of using the sunlight to focus the excitation waveguide 3 (ie, doped glass) and compare it with the result of 10 Omw 98 Onm pumped laser excitation waveguide 3 (ie, erbium-doped glass). : 1. When the weather is cloudy at noon and the temperature is 30 degrees Celsius, a 30cm * 30cm acrylic full-face Fresnel lens focusing plate is used to focus the sunlight sideways on the waveguide 3 (Ie erbium-doped glass), and use a spectrum analyzer to measure this waveguide 3 (that is, the optical amplification effect of erbium-doped glass Γ (stimulated and spontaneous radiation is measured directly without using a focusing lens) to obtain the first 11 The optical gain spectrum of 1.54 μπι wavelength can reach about -40 dBm, of which the depression near 1.4μm is caused by the band absorption of the acrylic material. 2. Using a 980nm pump laser to operate at 206 mA Under the current, 100 mw energy was measured through a power-meter, and this 20 200531299 energy was excited in the lateral excitation mode and the same experimental conditions to excite the waveguide 3 (ie, erbium-doped glass) to obtain the first 1 2 graph of gain frequency Spectrum, where the spontaneous amplified radiation (ase) energy of the erbium-doped fiber amplifier at 1.53 nm is about -42 dBm. Comparing Fig. 11 and Fig. 12, we find that a 30cm * 30cm Fresnel focusing plate excites the waveguide 3 (ie, erbium-doped glass) with a laser capacity of at least 100 nm and a 98-nm pump laser. Moreover, when sunlight is focused on waveguide 3 (ie, erbium-doped glass), not all of them are large because of the large beam. Energy into waveguide 3 (ie, bait-doped glass); in contrast, the 980 nm pump laser, because it is output from the optical fiber, can output a very strong energy in a smaller area to make waveguide 3 (ie, doped with bait). Bait glass) gets a higher particle population inversion. Therefore, by using the method of focusing the sunlight, the excitation effect of the usual high-power 980 rnn pump laser can be easily achieved. Therefore, once the solar optical amplifier is popularized and popularized, , It should be able to produce major technical reforms in optical communications (especially satellite optical communication Λ and terrestrial wireless optical communication). However, the above is only a preferred embodiment of the present invention.
