All-optical devices such as optical filters, (de)multiplexers, switches, modulators and optical buffers etc. have been demonstrated either on silicon or hybrid silicon platform. Power consumption, speed of operation, bandwidth and footprint etc. are important performance metrics for on-chip interconnects. Here we present the experimental and theoretical analysis of the performance of an all-optical gate, realized on III- V/SQl platform, for its applications in on-chip photonic interconnects
