Subpicosecond all optical switching in passive and active gallium arsenide/aluminum gallium arsenide nonlinear directional couplers.
Subpicosecond all optical switching device is pursued using a passive GaAs/AlGaAs multiple quantum well nonlinear directional coupler and an active GaAs/AlGaAs nonlinear directional coupler. A passive device showed all-optical switching from 2:1 contrast ratio to 2:3 with optical pulses detuned belo...
