Method of stabilizing the wavelength of lasers and a wavelength monitor |
摘要 |
A method of stabilizing the wavelength of lasers comprising a control circuit is proposed, wherein the light of the laser passes through a splitter and the split light passes through a wavelength filter in a first branch, and the light of both branches is in each case received by a photodetector. The photodetector of the first branch can be operated with different gain factors. The wavelength filter has a free spectral region which is greater than the spacing between the individual wavelengths in a wavelength division multiplex.
