Array-Type High-Speed and Large Detection Area Integrated Wireless Optical Receiver

A new high-speed and large detection area integrated wireless optical receiver is proposed. It is composed of a large number of identical optical receivers, each consisting of a high-speed photodiode and a subsequent low-noise amplifier. The output signals of all receivers are combined by an adding circuit so that the signal-to-noise power ratio (SNR) can be improved significantly. Estimates for the achievable data rate as a function of distance between transmitter and receiver are calculated.
