A Photon Limited SiPM Based Receiver for Internet of Things

Abstract

We compared two photons counting readout methods on a SiPM based receiver. The results show that integration method performs better BER in non-linear counts and 1Mbps is achieved under 9.44M0-9W with 11.78 photons per bit.

A Roadmap for Gigabit to Terabit Optical Wireless Communications Receivers

“…These narrower, fast output pulses are typically an order of magnitude narrower than the output pulses of other SiPMs. Since this significantly reduces ISI at higher data rates, SiPMs from onsemi have often been used to create receivers [ 5 , 6 , 7 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ].…”

“…An important performance parameter for any communications system is the bit error rate (BER), which depends upon the signal-to-noise ratio (SNR) at the receiver’s output. An approach to increasing the SNR of an OWCs or VLCs system is to use silicon photomultipliers (SiPMs) in the receiver [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. These devices are arrays of microcells, containing a single-photon avalanche diode (SPAD), that are designed so that an output pulse is generated whenever an avalanche event occurs.…”

“…The performance of receivers containing commercially available SiPMs can be determined experimentally [ 3 , 4 , 5 , 6 , 7 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. Ideally, the results of these experiments could be used to inform the selection of the best SiPMs from amongst those that have different characteristics.…”
