Mie-driven free-space electro-optic transducers

Since the emergence of nanoscale photonic systems to tailor light at-will, electro-optic transducers have become critical components to link the optical domain further with the electronic domain. Many electro-optic transducers have been reported for integrated photonic circuits that are ideally suited for fiber-based applications. Instead, free-space electro-optic transducers could target entirely different applications that require a combined in-plane and time-domain control of freely propagating light at high speeds. Here, we demonstrate nano-engineered free-space electro-optic transducers that combine low-loss dielectric Mie resonators arranged into a meta-array and high-performance electro-optic molecules. We discuss how various design parameters influence the tuning of optical resonances which we show to reach up to 20 nm at a center wavelength of 1550 nm.
