We demonstrate a photonic bistable spiking circuit with a graphene excitable laser for cascadable logic. This technology could be a potential candidate for applications in novel all-optical devices for information processing and computing. Photonic neuromorphic processing exploits the biophysics of neuronal computation algorithms [1] to provide a wide range(More)
We report on photo-detectors consisting of an optical waveguide that incorporates a resonant tunneling diode (RTD). Operating at wavelengths around 1.55 μm in the optical communications C band we achieve maximum sensitivities of around 0.29 A/W which is dependent on the bias voltage. This is due to the nature of RTD nonlinear current-voltage characteristic(More)
