Abstract

The Optical path length of an input/output optical waveguide in a Si ring filter is reduced to shorten the feedback loop length of an optical negative feedback laser. Thanks to the increase in phase margin in the optical negative feedback system, the spectral linewidth of a single-mode semiconductor laser can be reduced to 99.8 kHz.
