Example Embodiment
[0005] The invention mainly solves the integrated manufacturing of the modem and the feedback laser module: the distributed feedback semiconductor laser is to place the grating in the active area of the semiconductor laser instead of the reflective surface for reflection. The optical oscillation with the same wavelength as the grating's natural wavelength is selected in the spectrum, so that the single longitudinal mode laser is output.
[0006] The light-emitting device in the feedback light source is the feedback laser, which can be roughly divided into 1310nm, 1550nm, CWDM, DWDM and other light sources according to different operating wavelengths and uses. First, the invention greatly improves the short-term stability and long-term stability of the output optical power by adopting precise secondary refrigeration technology and photoelectric separation and other structural design technologies on the basis of the technology of the feedback type high-stability light source; ...
