Modulation instability of surface plasmon polaritons in graphene double-layer structure

A physical model of compact generator of infrared surface plasmon polaritons based on a planar waveguide structure to produce short pulses with a controllable repetition rate is proposed. The pulse generation is produced by modulation instability of continuous surface plasmon polariton waves in a film structure with graphene sheets (two graphene sheets spatially separated by a dielectric layer).
