    Abstract: 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 1014 cm−2 across 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 cm2/(V·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.

    Abstract: Electrical control of the emitter of a coupled quantum emitter-resonant cavity structure is provided. Electrodes are disposed near a semiconductor quantum dot coupled to a semiconductor optical cavity such that varying an applied bias at the electrodes alters an electric field at the quantum dot. Optical input and output ports are coupled to the cavity, and an optical response of the device relates light emitted from the output port to light provided to the input port. Altering the applied bias at the electrodes is capable of altering the optical response. Preferably, the closest electrode to the cavity is disposed between or away from angular lobes of the cavity mode, to reduce loss caused by the proximity of electrode to cavity. The present approach is applicable to both waveguide-coupled devices and non-waveguide devices.

    Abstract: Aspects of the disclosure are directed to optical microcavities and emitters that are spectrally aligned in an arrangement having an array of such microcavity-emitter combinations. The spectral alignment can be selective, in that a portion of the array of microcavity-emitter combinations, or a single microcavity-emitter combination, can be individually spectrally aligned. In specific examples, light is coupled within a semiconductor device having wavelength-dependent structures and optical cavities optically couple to the wavelength-dependent structures. One of the optical cavities and a wavelength-dependent structure are spectrally aligned, independent of another of the optical cavities.
