C «tT Ji Background Many applications need to control, for example, a planar waveguide illuminator circuit to be combined with an optical fiber, a light source such as a laser, and the propagation of light waves in a detector, while other applications require a The fiber is combined with another fiber. Unfortunately, many of these applications have a number of disadvantages and must be handled with great care. For example, direct connection of a fiber to a laser may be interrupted because the operating temperature of the field will rise and cause different 15 dimensional changes in the fiber and laser, respectively. Dimensional changes due to temperature rise can cause or change the position of the fiber relative to the laser. • Direct bonding is usually not sufficient because the dimensions of the pilot mode in the laser are different in the laser. This lack of sufficiency can often be overcome by focusing a laser or laser lens into the fiber from a laser. 20 However, 'light-conversion also has a misalignment caused by the use of a lens or a lens group, and the misalignment of the mechanical displacement can improve the fiber bonding. Improved fiber manufacturing method == 'To make the lens and the laser reach The alignment of _ is difficult. : 2: The ruler produced as the ambient temperature rises after a period of time. Therefore, there is a need for a 5 1282447. SUMMARY OF THE INVENTION The present invention provides an economical method for fabricating an optical fiber having a lens formed at at least one end thereof. 5 At least one end of the fiber can be changed, for example, using a material removal method to form a tip or "end point." The end point can be further processed in accordance with the present invention to produce a controllable focal length lens at the end point, and the fiber having the mirrored end point fabricated by the method of the present invention can be optically aligned with other fibers and the optical fiber is compared It is easily combined with light 10 devices such as light sources, planar waveguides, and optoelectronic circuits. One feature of the present invention is to provide a method of fabricating a fiber optic member, the method comprising coupling at least one end of a fiber optic member; and applying energy to the altered end of the fiber optic member to form a lens surface. Another feature of the present invention is to provide a method of fabricating a fiber 15 having a mirrored end point, the method comprising: providing a light transmissive cylindrical fiber; and etching the first end of the light transmissive cylindrical fiber to form one end point. Next, the end point is heated to form a lens surface at the heated end. Yet another feature of the present invention is to provide an optical fiber comprising a first lens surface formed on a first end of a light transmissive cylindrical optical fiber. The 20 lens surface is formed by changing at least one end of a fiber member; and applying energy to the modified end of the fiber member to form a lens surface. The method of the present invention for forming an optical fiber having a mirrored end point can control the lens radius and focal length at the end point at an economical price, and the fiber having the mirrored end point can be more easily combined with other optical fibers or such as a light source or a plane. The waveguide and the optical product body 1282447 are electrically separated from each other. Because each fiber includes - removed. 2 'So the lens can be (4) from the majority of the fiber optic package, the lens can reduce the number of components, and can be misaligned between many lenses or groups of lenses encountered in a typical optical closure The secret is secret. Reducing the number of components can be obtained - (d) single optical single two and the reduction usually occurs in the fresh component seal "manufacturing process and human: the expensive cost, and the silk can be made smaller than the t ^ size table can not be more Conveniently implemented - a compact system and a lower cost. - 10 15 20 The present invention is defined by the following patent application pillow, which is hereby incorporated by reference herein in DETAILED DESCRIPTION OF THE INVENTION The present invention will be more fully understood by those of ordinary skill in the art of the present invention, and other advantages of the present invention will be understood.

Embodiments of the present invention and its advantages can be best achieved by referring to the following detailed description. It is to be understood that the similar elements shown in one or more of the figures are represented by like reference numerals..:: Embodiment 3 10 Detailed Description Figure 1 shows an embodiment in accordance with the present invention for A process 100 for forming a mirror-end point on an optical fiber, and the process 1 can include providing a single or-beam cylindrical member (sU) 2), such as a cylindrical rod made of glass (called), plastic, or the like. Or fibers. 15 20 The first end of each cylindrical member may be altered by removing material to form a coin end, a modified end or a tip (slG4). In an embodiment, the endpoints are Wait for each end of the __ piece to accept - (4) bath or liquid Formed by a reactive spray of a body spray. In the embodiment, a cylindrical member: a small portion is immersed in a liquid bath containing a material removal or (iv) liquid. In another embodiment... suitable material Spraying at least one of a cylindrical member. 'Removed from each member segment = material removed from the periphery at the end of the cylindrical member is generally shaped 8 1282447, in an embodiment The second end of each cylindrical member may also be treated with a liquid = or - liquid spray reactive liquid. The second end of the cylindrical member is at least partially immersed in a liquid bath comprising an etching liquid, and in another embodiment A suitable etch liquid is sprayed onto the second end 5 of the cylindrical member. The removal material will form a _ tip at the second end of the cylindrical member. In the case of the shell member, the tip of the cylindrical member may be Energy treatment to heat the tip. Heating the tip, as will be described in detail below, allows the lens surface to be formed on the tips. Fig. 2 is a simplified view of the engraving of a plurality of cylindrical members 10, 02, in accordance with an embodiment of the present invention. In an embodiment, each of the cylindrical members may be; a rod, a cylinder, a fiber, or other similarly shaped member. Alternatively, the circle member may have or be pre-changed into a non-circular cross section such as a square or other polygonal cross section, and the non-circular cross sectional views are more suitable for use in certain planar waveguide, optoelectronic, and optical devices. 15... The diameter and length of each of the round (four) members 202 is generally determined by the application. The diameter of each of the cylindrical members 202 can be the diameter of a standard single mode fiber, and has a typical i. Burn the full diameter of 125μιη. Depending on the application, typically the Jlkd of each cylindrical member 2〇2 can be between about (10) (four) and about a few millimeters. In another twenty embodiment, 20 can be a mode fiber. In one example, the end 204 of the cylindrical member 202 can be altered by removing the material. For example, in accordance with the present invention, a cost engraving process is used. Referring again to Figure 2, in one embodiment, the change in end 2〇4 can be accomplished by placing the end 204 into a liquid bath 206. The liquid bath 206 can comprise any formulation suitable for the necessary chemicals to remove material from the fibers' and in one embodiment, the liquid bath 2〇6 comprises hf acid 2〇8. A thin layer or oil can be attached to the liquid bath 206, thus forming an oil film 210 on the surface of the HF acid 208. The addition of the oil film 210 to the surface of the acid 2〇8 creates a barrier on the acid surface to control the depth of the etching process. Usually, the sphericity of the money is controlled by the immersion depth of the end portion 204, but the hf uric acid sometimes "crawls up", by immersing in the part of the ^^ acid, causing non- Unnecessary etching of the immersed portion. The oil film 21〇 acts as an etch stop and prevents 10 HF acid from creeping beyond the oil film 210. - Place the end portion 204 in the liquid bath 206 for a period of time sufficient to remove the required amount of material The time required to remove the material is a function of the material composition of each cylindrical member and the composition and concentration of the liquid bath 2 〇 6. In one embodiment, as shown in Figure 3, each cylindrical member 2 〇2 includes 15 a core region and a peripheral region P1 surrounding the core region q. When φ is operated, the liquid bath 206 affects the peripheral region before it affects the core region.
Pi，因為該周邊區域？〗直接接觸!^酸2〇8且對^^酸2〇8有較 大之暴露表面積。這種情形在角落區域3〇2特別明顯，因為 該等角落區域之頂部與側邊同時暴露出來。所使用纖維種 2〇類亦會影響該尖端區域如何形成，且某些纖維之芯區域口 係作成比該周邊區域P]更純—較不純的區域比較會被該液 體移除材料。 °亥改變^304之長度L係利用例如，構件202浸入hf酸 2〇8中且在油膜210下方之深度來控制。但是’改變端3〇4之 1282447 銳利度（或斜度)S係利用構件202被固持在液體浴206中之時 間長度與HF酸208之濃度來控制。 有利地，本發明之材料移除製程是一缓慢的製程，因 此，製造者可以連續地檢查材料移除製程之進度，且可以 5在端部3〇4達到所需尺寸之任一時間使端部2〇4與液體浴 206分離。 由該材料移除製程所產生之結構是尖端構件4〇〇，如第 4A圖所示。Pi, because of the surrounding area? 〖Direct contact! ^ Acid 2〇8 and a larger exposed surface area for ^2 acid. This situation is particularly noticeable in the corner regions 3〇2 because the top and side edges of the corner regions are simultaneously exposed. The type of fiber used also affects how the tip region is formed, and the core region of some fibers is made purer than the peripheral region P] - the less pure region is removed by the liquid. The length L of the ° change ^304 is controlled by, for example, the immersion of the member 202 in the hf acid 2〇8 and the depth below the oil film 210. However, the 1282447 sharpness (or slope) S of the altered end 3〇4 is controlled by the length of time the member 202 is held in the liquid bath 206 and the concentration of the HF acid 208. Advantageously, the material removal process of the present invention is a slow process so that the manufacturer can continuously check the progress of the material removal process and can either end the end 3 〇 4 to the desired size. The portion 2〇4 is separated from the liquid bath 206. The structure resulting from the material removal process is the tip member 4A, as shown in Figure 4A.

The location of the heating and the amount of energy applied to the tip will determine the physical shape and radius of the lens surface 408, and thus the focal length of the lens surface 408 formed at the tip 402. The method for applying the energy required to form the end point cleaning & lens can use an appropriate energy generating device including heat (ie, flame), electric spark, and the following embodiments, and the following embodiments. The effect is achieved. 20 Referring again to Fig. 4B, in the case of the yt, the tip end 402 of the tip member 400 can be placed in the ridge arc generating device 406 of the splicing tool. The arc generating device 406 can provide an arc or spark for achieving heat treatment of any predetermined light transmissive member, and the heat treatment can form the lens surface 11 1282447 from the foregoing manner. In other embodiments, the energy source 410 providing thermal energy can be A glow discharger placed near the tip 402 or a high energy laser using a wavelength that can be absorbed by the material of the tip 402 to heat the material and form the lens surface 408 of the present invention. 5 Figure 4C includes a side view of a single light transmissive tip 402 after a heating process in accordance with an embodiment of the present invention. The tip 3〇4 can be varied using the heating process to have different curvature radii in two mutually perpendicular or other directions. Specifically shown in FIG. 4C are curved surfaces 412a, 41A and 412, for example, elliptical, semi-elliptical, flat/convex 10 non-spherical shapes formed at different positions on the tip 402, and the curved surfaces 412a, 412b and 412c can provide different optical properties on different optical axes relative to the major axis of lens surface 408. The position of lens surface 408 on tip 402 is a function of the depth of energy or heating applied along the length L of tip 4〇2 and the length of time exposed to the energy source. In one embodiment, tip 402 has a length L. The energy system is applied at a position of length l 15 to form a lens surface 4 〇 8 at the position on the tip 402. In an embodiment, the position along the length of the lens surface 4〇8 may have a position of about 15. To about 20. The angle or slope between them is particularly useful when applied to fiber or waveguide bonding and packaging. The curvature and size of the lens surface 408 can be adjusted according to the needs of the particular application 20 so that the manufacturing specifications and tolerances of the lens surface 408 are governed by a particular control and defined by the end user.
