Abstract: Embodiments of the present disclosure describe an underwater optical communication and illumination system employing laser diodes directly encoded with data, including spectrally efficient orthogonal frequency division multiplex quadrature amplitude modulation (QAM-OFDM) data. A broadband light source may be utilized to provide both illumination to an underwater field of interest and underwater optical communication from the field of interest to a remote location.

Abstract: An optical mirror diversity receiver for a visible light communication system is provided with an array of photodiodes each having an optical-signal-receiving area, with a mirror positioned between an adjacent pair of photodiodes to preferentially redirect light toward one of the photodiodes while also blocking light that would otherwise be received at the photodiode. An angle-aided mirror diversity receiver is also provided with surfaces of the photodiodes aligned relative to the mirror to yield reductions in correlation.
