Abstract
Spectral characteristics for 1.3¿m monolithic external cavity (MEC) DFB lasers have been studied experimentally. As drive current increased, light output and spectral linewidth were changed periodically. Less than 2 MHz linewidths were obtained at the minimum points of each period. The narrowest beat spectrum linewidth was less than 3MHz with two MEC DFB lasers.
