Abstract

A demonstration of frequency-difference stabilization over a 100-GHz range for two distributed-feedback laser diodes (LD's) by utilizing a loss-compensated optical loop with a frequency shifter is given. Emitted from a master distributed-feedback LD, a light wave is modulated into a pulse. Around the optical loop to shift its frequency to the difference required between the master and slave distributed-feedback LD's, the pulse is then circulated. With the frequency-shifted pulse, a continuous-wave pulse from the slave LD is mixed, and with a conventional low-speed heterodyne receiver, their beat frequency is measured.
