Abstract

Among several integrated all-optical devices proposed to date, the nonlinear directional coupler (NLDC) has received considerable attention.1 Experiments have demonstrated self-switching of light in semiconductor NLDCs with cw2 or picosecond excitation.3 It appears that two main drawbacks may hamper the cascadability of passive semiconductor NLDCs and thus their application to future optical circuits: pulse breakup and absorptive losses.
