Small signal analysis of frequency chirping in injection-locked semiconductor lasers

S. Piazzolla, P. Spanò, Mario Tamburrini

Abstract

A theoretical and experimental investigation of frequency chirping in injection-locked semiconductor lasers under a condition of small signal modulation is presented. It shows that a substantial reduction of frequency chirping can be obtained which, however, is effective only up to modulation frequencies of the order of the locking bandwidth and is strongly dependent on the frequency detuning between master and slave.
