A reflective spatial light modulator (SLM) made of an electro-optic material in a one-sided Fabry-Perot resonator can provide phase and/or amplitude modulation with fine spatial resolution at speeds over a Gigahertz. The light is confined laterally within the electro-optic material/resonator layer stack with microlenses, index perturbations, or by patterning the layer stack into a two-dimensional (2D) array of vertically oriented micropillars. Alternatively, a photonic crystal guided mode resonator can vertically and laterally confine the resonant mode. In phase-only modulation mode, each SLM pixel can produce a &#x3c0; phase shift under a bias voltage below 10 V, while maintaining nearly constant reflection amplitude. This high-speed SLM can be used in a wide range of new applications, from fully tunable metasurfaces to optical computing accelerators, high-speed interconnects, true 2D phased array beam steering, beam forming, or quantum computing with cold atom arrays.

Modulating graphene's optical conductivity with an electrolyte nanopatterning technique reduces or eliminates scattering loss caused by rough edges from etching. This technique uses a resist mask patterned with features as small as 30 nm to shield graphene from ions in an electrolyte. It can provide a carrier density variation of about 10cmacross a length of just 15 nm. And it can be combined with a technique of growing or transferring graphene on atomically smooth hexagonal boron nitride (hBN) to increase graphene's carrier mobility, e.g., to 10,000 cm/(V&#xb7;s) or more. The resulting graphene metamaterials can be used to make voltage-tunable electro-optical devices, such as beam-steering devices, electro-optical switch and modulators, and reconfigurable holograms.
