Abstract
Effect of in-phase and antiphase gain-coupling on high-speed properties is studied for MQW DFB lasers with periodically truncated quantum-wells. The enhancement of modulation bandwidth due to antiphase gain-coupling is found significantly suppressed, and gain-coupled DFB lasers with high /spl kappa/L are preferred for large modulation bandwidth due to the presence of linear gain saturation in MQW lasers.<>
