Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity via an optical wireless communication link, a first optical wireless signal using photodetectors positioned on a photodetector panel of the UE. The photodetector panel may include a hole around which the photodetectors are positioned and may be located a first distance from a curved optical device of the UE via which the first optical wireless signal is received. The UE may transmit, to the network entity via the optical wireless communication link, a second optical wireless signal using a light source of the UE that is located a second distance from the curved optical device via which the second optical wireless signal is transmitted. The second optical wireless signal may pass through the hole in the photodetector panel based on the second distance being greater than the first distance.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) in an optical wireless communications system may utilize a curved focal plane of a condenser lens to communicate an optical wireless signal. An optical front-end (OFE) of the UE may include one or more optical communication components located at varying distances from the condenser lens on a curved focal plane of the condenser lens. Additionally or alternatively, the UE may adjust a position of one or more optical communication components on the curved focal plane. Additionally or alternatively, the OFE may include an array of condenser lenses and optical communication components each optically coupled with one or more condenser lenses. The UE may perform equal gain combination and/or equal ratio power splitting to communicate an optical wireless signal using the array of condenser lenses and optical communication components.
