A real-time SiPM-based receiver for FSO communication


Silicon photomultipliers (SiPMs) are photon-counting detectors based on single-photon avalanche diodes which have the potential to detect single photons in the visible spectrum. In this paper, we present an embedded real-time communication system based on the Xilinx Zynq-7000 FPGA platform with a 1mm-sq SiPM demonstrating the full potential of low power single-photon communication. The experimental results show that the implemented real-time system archives a Bit Error Rate (BER) smaller than 10-3 with 1.1nW of incident optical power at 100Kbps. In addition, the SNR calculation under different optical power is compared to the theoretical SNR to demonstrate the system’s dynamic range.
