Abstract :
In this paper, we report the experimental results of efficient nonlinear polarization switching in a single quantum well amplifier and show that the numerical simulations based on a simple model agree reasonably well with the experimental data. The sample consisted of an InGaAs well, GaAs barriers, and graded AlGaAs cladding layers. It lased at 974 nm. The electro-luminescence shows a peak near 970 nm in the TE mode and a peak near 940 nm in the TM mode
