As shown in Figure 6, be a kind of concrete Laser output system embodiment.Whole system is made of RSOA array (RSOA array), two AWG, optical splitter (Splitter) array, modulator array (Mod array) and image intensifers.Wherein, the passive devices such as AWG and Splitter can be integrated on the same optical chip with the PLC technology; RSOA array and modulator array can by the technique of losing money instead of making money of maturation, be integrated on the PLC chip.Image intensifer can be arranged on PLC outside (mode shown in this figure) according to different demands, perhaps is integrated in the PLC chip internal.Optionally, output place one side of the upper AWG1 with the RSOA array of PLC is provided with part reflection (PR, Partial reflection) film; Perhaps the output at AWG1 increases a partially reflecting mirror.
Wherein, each RSOA is with part reflectance coating or the laser instrument of partially reflecting mirror formation on AWG1 and the PLC.The wavelength of this laser instrument is by the wavelength decision of AWG1 output port.Same, the number of wavelengths of this multiple-wavelength laser, wavelength interval, also port number and the wavelength interval by AWG1 determines.Therefore, as long as by the different AWG1 of design, can produce different multi wave length illuminating sources.Such as, in the application of 10G PON, can design the 200GHz interval, penetrate four wavelength interval 200GHz of generation so that swash.Need to prove, the wavelength interval of this AWG is designed, and does not need to satisfy the wavelength regulation of ITU, only need to aim at the AWG2 that is arranged on this PLC to get final product.
Because the laser source wavelength in this system is fully by the AWG1 decision, therefore, AWG1 is by selecting suitable material, and the design through special can realize that its optical characteristics is insensitive to variations in temperature than being easier to.At last, realize the output wavelength of whole system, insensitive to the variation of temperature.Thereby can remove the very large TEC of power consumption, to reduce the power consumption of LASER Light Source and whole system.

Make the material of PLC, include but not limited to silica (SiO
2), organic polymer (Polymer) and silicon (Si).With SiO
2Material is example, and very ripe making optical splitter and the technique of AWG have been arranged now.
Two AWG in the said structure need to satisfy varying with temperature insensitive requirement, in order to remove the temperature control of chip.It is identical that two AWG can be designed to, and also can design differently.Optionally, can be designed to AWG1 the passband structure of Gaussian, AWG2 is designed to the passband structure of flat type.
Optionally, optical splitter Splitter can be realized by multimode interference MMI, the perhaps Y splitter of cascade and other structures realization.
As for modulator, can be electroabsorption modulator, also can be the MZ performance of interferometric modulators, two kinds of embodiment schematic diagrames are respectively as shown in Figure 7 and Figure 8.Among Fig. 7 and Fig. 8, optical splitter is realized by MMI.Among Fig. 7, modulator is realized by EAM, therefore, forms electroabsorption modulator array (EAM array).Among Fig. 8, modulator is realized by MZI.By EAM or MZI, realize the modulation to optical splitter output light splitting.If adopt MZI, under specific PLC material, such as Si, this modulator can directly be produced on the PLC, and need not to mix integrated again.In this case, on the PLC chip, integrated AWG simultaneously, Splitter and modulator array further reduce cost.
As shown in Figure 9, be the concrete Laser output system embodiment of another kind.This embodiment only is in the realization of multiple wavelength laser light source with the difference of system shown in Figure 6.Among this embodiment, still take 16 road light sources as example.Wherein, multiple wavelength laser light source is realized by the Bragg grating (λ 1 ~ λ 4) of four cascades by a gain media.Each Bragg grating can select specific wavelength to reflect; A plurality of cascades namely can be reflected a plurality of wavelength, realize that finally the sharp of a plurality of wavelength penetrate.Because Bragg grating itself just has reflex, therefore need not again at PLC end face plating reflectance coating.In addition, the wavelength of each Bragg grating, each input channel wavelength of the AWG2 among needs and the PLC is aimed at.
Among above-mentioned each embodiment of the present invention, vary with temperature insensitive filtering device by gain media and optical characteristics and formed laser instrument, thereby eliminated the impact of temperature on laser output wavelength, realized device without refrigeration work, reduced power consumption and cost; By the PLC technology, realize the integrated of multichannel light source, reduce encapsulation and Material Cost, reduce the size of multichannel light source, be conducive to support in the same ply-yarn drill more port; Utilize image intensifer, multi wave length illuminating source is amplified, improve the Output optical power on every road.
