Enhanced Third-Order Nonlinear Effects In Ultra-Compact Algaas Nanowires

Abstract

The self-phase-modulation enhancement of AlGaAs nanowires due to strong confinement was investigated. The prototype structures fabricated were a few hundred nanometers wide and up to 0.7 mm long. The tapers were also fabricated for efficient modal excitation and output collection. The spectral evolution of of 8ps transverse magnetic (TM) polarized pulses was studied to evaluate nonlinear response. The nonlinear phase shift in the nanowire was found to dominate the spectral evolution. The nonlinear phase shift of π were obtained for effective nanowire length of 0.35 mm at 30 W. The nonlinear propagation was modeled in the sub-wave-length guiding structures and was observed to be same as that of the experimental data.
