Paper Abstract

A time-domain traveling wave algorithm is extended to investigate high-order quantum dot based laterally-coupled distributed feedback semiconductor lasers. The effect of radiation modes in laser performance is included via Streifer’s terms. We calculate the optical gain spectra based on a coupled set of rate equations and taking into account both inhomogeneous broadening due to dot size fluctuation and homogeneous broadening due to polarization dephasing. It was found that, for third-order quantum dot based laterally-coupled distributed feedback lasers; a stable single mode operation with high SMSR can be achieved by means of fine tuning of the grating duty cycle
