Scientists report the observation of ultralow-power resonant optical bistability, self-induced regenerative oscillations and coherent four-wave mixing in graphene–silicon hybrid optoelectronic devices at cavity recirculating energies of a few femtojoules. The findings indicate the feasibility and versatility of such devices for use in next-generation chip-scale high-speed optical communications, radiofrequency optoelectronics and all-optical signal processing.
