Self-Seeding of DFB Laser to Improve the Frequency Response
-
Abstract
A simple and effective self-seeding method of DFB lasers is presented.The frequency responses of a directly modulated DFB laser become very flat with this self-seeding method.Experiment was done using a three-port optical circulator and a 1×2 optical coupler.The results show that the peak of relaxation oscillation of the frequency response curves can be restrained significantly by changing the polarization of the self-seeding light. -
