Techniques for applying one or more terahertz transceivers in wearable display glasses are described. The one or more terahertz transceivers operate signals in Terahertz. When used on a pair of display glasses, these transceivers allow the display glasses to communicate with other devices wirelessly, including receiving/transmitting image date.

The present invention concerns a photo-driven display, reflective display comprising first and second electrode layers, a photoconductor layer, provided between said electrode layers, said photoconductor layer comprising a material that is sensitive to infrared light, and an electrochromic material layer.

An apparatus embedded with one or more terahertz transceivers is described. The one or more terahertz transceivers based on at least Gunn diode are provided to facilitate wireless communication in the apparatus, where the apparatus is embedded with one or more planar antennas. The transceiver operates in terahertz and may be coupled to one or two different antennas, one for transmission and the other for reception.

An optical device includes a photonically controlled Josephson Junction and a Faraday rotator cell magnetized by the Josephson Junction.

Techniques for using one or more terahertz transceivers in wearable display glasses for bio-sensing are described. The one or more terahertz transceivers operate signals in Terahertz and configured as transmitters or receivers. When disposed collaboratively on a pair of display glasses, these transmitters or receivers allow THz signals to radiate certain locations of a human head and receive reflections thereof. The received signals may be used to detect/derive various bio conditions (e.g., brain condition).

Methods, devices, and systems for managing programmable photonic waveguides are provided. In one aspect, a method includes: varying respective localized electric fields across a plurality of regions of a waveguide core of a waveguide structure of a programmable photonic waveguide to cause corresponding local variations in at least one of a refractive index or a nonlinear susceptibility of the waveguide core, and programming an optical signal by coupling the optical signal through the waveguide core with the corresponding local variations in the at least one of the refractive index or the nonlinear susceptibility of the waveguide core.
