Second Harmonic Generation Enhancement from Isolated Selenium Nanowire Coupled to Mie Resonant Silicon Disks

Optical coupling between heterogenous nanophotonic structures is a promising approach to enhance nonlinear optical response. Here we demonstrate second harmonic generation enhancement by 152-times from an isolated Selenium nanowire coupled to a silicon disk supporting Mie Resonances while maintaining the polarization selectivity of the nanowire.
