ABSTRACT:
The light-emitting device has a fiber stub part, a semiconductor optical amplifying device, a photodiode, and a bench as its main parts. The fiber stub part is composed of a ferrule and a grating fiber. The fiber stub part and the semiconductor optical amplifying device are mounted on the bench, and optically coupled together. An optical cavity is composed of the light-reflecting face of the semiconductor optical amplifying device and the diffraction grating of the grating fiber. The light-emitting device, which does not use a pigtail fiber, can be downsized and can provide laser light with a desired wavelength.
