We demonstrate an optical link operating in
indoor ambient lighting conditions using a CMOS
single photon avalanche diode (SPAD) optical receiver
and a RGB light emitting diode (LED). The high
sensitivity of the SPAD receiver allows the link to
operate at 2 m distance at a total 60 Mb/s and bit error
rate (BER) of 1×10-3 without lensing. The transmitter
implements color shift keying (CSK) using a custom 4-
channel current mode CMOS digital to analog
converter (DAC). The miniaturized, low cost
components employed at transmitter and receiver are
suited to integration in portable electronic devices or
chip-in-a-bulb respectively.
