纳米尺度的光源在下一代通信，传感，成像，微纳加工以及数据存储领域都有广泛的应用，而光源的芯片级电可调控性是一个实用的功能。

我们利用单晶硫化镉纳米带(CdS nanoplate)独特的双光子吸收光致发光能力和较大的二阶光学非线性系数，以及MEMS式微光机电腔具有的高效率电可调控性，实现了芯片级电调控双波长可见光源。该工作有望为下一代片上电可调控光源提供一种技术路径。

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.
