Abstract

A complete design of 1.3 μm AlGaInAs/InP narrow stripe semiconductor lasers for self-pulsating operation is realised by using a 2×1D simulation model. This numerical model is based on the effective index method and self-sustained pulsation mechanism in the narrow stripe lasers. The self-pulsation effect is enhanced by the self focusing and defocusing of the optical field which is dependent on the modification of carrier densities in the active region. The resulting AlGaInAs-InP device with compressively strained multi-QWs showed self-pulsation frequency of 3.5 GHz.
