Our scheme allows for strong photoluminescence enhancement with polarization-spatial multiplexing and lifetime reduction, offering potential for ultrafast modulation.2enPublisher Copyright: © 2017 IEEE.Enhanced and directional photoluminescence from doubly-resonant WSe<sub>2</sub>-Si hybrid structure2017-10-2510.1364/CLEO_QELS.2017.JTh2A.10585044192139
