Abstract :
Summary form only given. We report the experimental and simulation results of the wavelength dependence and cross polarization effects of nonlinear switching in an all-semiconductor-optical-amplifier loop device. For input/output coupling, a multimode interference (MMI) amplifier was connected to the loop. The observed nonlinear switching comes from the combined effect of the nonlinear coupling in the MMI amplifier and the lateral wave field redistribution caused by the loop. The semiconductor optical amplifiers were fabricated on a four-period GaAs/AlGaAs multiple quantum well epitaxial structure.
