Optical wireless communication using a fully integrated 400 µm diameter APD receiver

An optical wireless communication (OWC) system is demonstrated which uses a highly sensitive lens-less optoelectronic integrated circuit with a 400 µm diameter avalanche photodiode as a high-speed receiver, and a transmitter with highly collimated steerable beam at 680 nm wavelength. The benefits of integrated receiver with large-area photodiode in an OWC scenario are proven experimentally. At a d...
