Abstract

The polarisation dependence of the optical gain in quasi-index-guided, γ = 1.3 μm, GaInAsP/InP, metal-clad, ridge-waveguide laser diodes is demonstrated. It is shown experimentally that, depending on the lateral waveguiding, either the TE or the TM-polarised mode is favoured. By appropriate design of the laser structure, almost polarisation-independent internal optical gain has been experimentally achieved.
