Abstract

We design and fabricate a simple ultracompact wavelength-controllable bi-directional optical diode. It consists of a silicon microring (nonlinear attenuator) and a directional coupler (linear attenuator). High nonreciprocal transmission (~24.2dB) is achieved. Negligible-penalty OFDM/OAM 64-QAM signaling through the diode is demonstrated.
