Abstract / Description of output

In this paper, an optical orthogonal frequency division multiplexing (OFDM) system based on a single-photon avalanche diode (SPAD) receiver is presented. SPAD detectors do not require a transimpedance amplifier as they operate in the
Geiger mode. This poses challenges on detecting continuous data carrying signals. However, in this work we show that OFDM signals can indeed be detected, and the bit error ratio performance of both DC-biased optical OFDM and asymmetrically clipped optical OFDM are investigated. The investigations are
carried out in the absence of background light. The results are compared to standard optical OFDM with photodiode receivers. The SPAD-based OFDM system shows superior power efficiency over the state-of-the-art counterpart, and it can reach receiver sensitivities that are comparable to existing radio frequency (RF) systems.
