Abstract
Next-generation optoelectronic devices require dynamic control over their functionalities while simultaneously being highly compact. This presents a problem, since conventional optoelectronics require bulky filters and optical elements to address the multidimensional components of light, including wavelength, polarization, and angle of incidence. To this end, optically resonant nanostructures provide a promising platform to tailor a device’s spectral responsivity as well as its angular and polarization sensitivity, without the need for external filters [1,2]. However, employing geometrical resonances for actively tunable devices proves to be challenging, since semiconductor materials tend to exhibit limited electrical tunability and the optical response is therefore fixed during nanofabrication.
