Abstract
We propose active metasurface devices where the state of emitted light is controlled by voltage. Based on the simulations of expected emission spectra, we present the concept of a light emitting device with the voltage controlled wavelength and degree of linear polarization of emission. The device combines the ability of metasurfaces to control light with a wavelength-tunable light source based on indirect excitons in coupled quantum well heterostructures.

Plasmonic metasurfaces exploring plasmonic resonances in a metal grating on a dielectric substrate are widely used for various purposes such as to enhance the efficiency of light emitting devices (LEDs),1 to magnify the light absorption in photodetectors2 and thin film solar cells,3,4 to control the intensity and directivity of light emission,5 to enhance the magneto-optical effects6–8 and the sensitivity of optical sensors for chemical gas detection and biosensing,9–11 to magnify nonlinear optical effects such as 2nd and 3rd harmonic generation,12 and in photochemistry
