摘要： Embodiments of the present invention disclose an optical transmitter, a wavelength alignment method, and a passive optical network system. For the optical transmitter, a 10 G-DML, an MPD 1, an MPD 2, a collimation lens, and a narrowband optical filter are disposed in a TO to achieve monitoring of an optical power, received optical powers are monitored by using the MPD 1 and the MPD 2, the detected optical powers are output to a wavelength locking monitoring circuit by using a TO pin, variations, which are detected by the wavelength locking monitoring circuit, of the optical power and a variation of a wavelength locking factor K0 are separately compared with corresponding thresholds, and a comparison result are sent to a wavelength locking control circuit, to enable the wavelength locking control circuit to adjust, according to the comparison result and by using the TO pin, a temperature of a TEC to perform wavelength alignment. Wavelength locking control is performed on a wavelength of a 10 G-DML and a filter by using a novel wavelength monitor loop, thereby achieving an objective of a high modulation rate with a low cost and low power consumption, where a chirp phenomenon is reduced.

摘要： A first contact surface (310) of a semiconductor laser chip (302) can be formed to a first target surface roughness and a second contact surface (312) of a carrier mounting (304) can be formed to a second target surface roughness. A first bond preparation layer (306) comprising a first metal can optionally be applied to the formed first contact surface, and a second bond preparation layer (308) comprising a second metal can optionally be applied to the formed second contact surface. Both preparation layers may be made of gold and diffusion bonding results from a heating of device under pressure. The first contact surface can be contacted with the second contact surface, and a solderless securing process can secure the semiconductor laser chip to the carrier mounting. Related systems, methods, articles of manufacture, and the like are also described.

摘要： A disclosed surface-emitting laser module includes a surface-emitting laser (40,340) formed on a substrate to emit light perpendicular to its surface, a package (21,321,521) including a recess portion in which the substrate having the surface-emitting laser is arranged, and a transparent substrate (22,322,522) arranged to cover the recess portion of the package and the substrate having the surface-emitting laser such that the transparent substrate and the package are connected on a light emitting side of the surface-emitting laser. In the surface-emitting laser module, a high reflectance region and a low reflectance region (111) are formed within a region enclosed by an electrode on an upper part of a mesa of the surface-emitting laser, and the transparent substrate is slanted to the surface of the substrate having the surface-emitting laser in a polarization direction of the light emitted from the surface-emitting laser determined by the high reflectance region and the low reflectance region.
