Electromechanically reconfigurable CdS nanoplate based nonlinear optical device.

2016 
Here, we report experimental demonstration of dynamic control and enhancement of second harmonic generation and two photon excited photoluminescence in CdS nanoplates via an electromechanically reconfigurable Fabry-Perot (FP) microcavity. Microcavity coupled CdS nanoplates can be configured as a single or dual wavelength nonlinear light source by tuning the pump wavelength while the output intensities can be tuned by the on-chip control voltage. Our work realizes a reconfigurable device platform with insight toward advanced optical devices based on semiconductor nanoplates for next generation on-chip tunable light sources, sensors and optomechanical systems.
