Gate-controlled optical bistability via tunable self-action feedback in a semiconductor quantum dot–graphene nanodisk hybrid

We theoretically examine how electrostatic gating can tune the steady-state response of a semiconductor quantum dot (SQD)-graphene nanodisk hybrid between monostable and bistable regimes. The model combines the optical Bloch dynamics of a driven two-level SQD with a gate-dependen...
