  • Receiver for low-power optical signals with operation in conditions of high incidence of background light and application in visible light communication
    Patent number: 11177882
    Abstract: The invention relates to an optical receiver for digital signals in the visible range, with a photodetector consisting of a two-dimensional array of avalanche photodiodes (APD), connected in parallel and with an output representing the sum of the individual responses of each APD. The photodetector requires a low on incidence power and therefore allows to detect specific optical signals in a very well-defined range of powers and frequencies, in real high intensity back light conditions without the requirement of optical filters, which allows a great advance in the utility and applicability of communication with visible light with digital modulation techniques.
