Gate-tunable frequency combs in graphene–nitride microresonatorsGate-tunable frequency combs in graphene–nitride microresonators, Published online: 11 June 2018; doi:10.1038/s41586-018-0216-xCoupling graphene sheets with a silicon nitride ring microresonator allows the nonlinear cavity dynamics to be altered by a gate voltage, resulting in tunable, chip-scale, optical frequency combs.
