Abstract
Optical receivers and transmitters can be used as stand-alone systems or combined together as a transceiver. Each of the receiver and transmitter may include an optically reflective steerable device, such as an optically reflective liquid crystal metasurface (LCM), to steer optical radiation to a target location. A transmit waveguide conveys optical radiation from a light source to the transmitter steerable device. A receive waveguide conveys received optical radiation reflected by the receiver optically steerable device to a sensor. In some embodiments, the transmit waveguide and the receive waveguide may be portions of the same planar waveguide. The receiver includes a holographic lens between the receiver LCM and the receive waveguide to pass through optical radiation received at a first range of incident angles and modify (e.g., collimate and/or spectrally filter) optical radiation reflected by the receiver LCM for conveyance by the receive waveguide to the sensor.
