摘要： A semiconductor laser module includes a semiconductor laser having an active region between a light-reflecting surface and a light-exit surface thereof, and an optical fiber optically coupled to the semiconductor laser and including an optical fiber diffraction grating. The optical fiber diffraction grating selectively reflects light within a predetermined wavelength band. The wavelength band has a width larger than a wavelength interval of a longitudinal mode of light resonating between the light-reflecting surface and the light-exit surface.

摘要： A semiconductor laser module in which: the distance between a semiconductor laser chip and a diffraction grating can be shortened; the light output spectrum is stabilized; and the output characteristic does not fluctuate due to the external condition. In the semiconductor laser module, a diffraction grating structure is constituted in an optical fiber by at least two diffraction gratings for reflecting light with different wavelengths respectively. The diffraction grating structure is formed in a place corresponding to the inside of the package or the inside of the coupling means.

摘要： A light generating module 1 comprises a housing 2, a semiconductor light-emitting device 4, a driving element 6, and a monitoring light-receiving device 8. The monitoring light-receiving device 8 is optically coupled with the semiconductor light-emitting device 4. The driving element 6 drives the semiconductor light-emitting device 4. The housing 2 contains the semiconductor light-emitting device 4, the driving element 6, and the monitoring light-receiving device 8. These elements 4, 6, and 8 are disposed sequentially along a predetermined axis. The driving element 6 is disposed between the semiconductor light-emitting device 4 and the monitoring light-receiving device 8. This configuration makes it possible to dispose the driving element 6 close to the semiconductor light-emitting device 4 so as to achieve a transmission rate of 10 Gbps without degrading the optical coupling between the semiconductor light-receiving device 8 and the semiconductor light-emitting device 4.
