Abstract

We demonstrate experimentally bright light emission from monolayer WSe2 coupled to Si doubly-resonant grating-waveguide structure. Our scheme allows for strong photoluminescence enhancement with polarization-spatial multiplexing and lifetime reduction, offering potential for ultrafast modulation.
