摘要：

This paper presents the first demonstration of InGaN multiple quantum well (MQW) based micro-photodetectors (mu PD) used as the optical receiver in orthogonal frequency-division multiplexing (OFDM) modulated visible communication system (VLC). The 80-mu m diameter mu PD exhibits a wavelength-selective responsivity in the near-UV to violet regime (374 nm -408 nm) under a low reverse bias of -3 V. The modulation scheme of 16-quadrature amplitude modulation (16-QAM) OFDM enables the use of frequency response beyond -3 dB cutoff bandwidth of mu PD. A record high data rate of 3.2 Gigabit per second (Gpbs) was achieved as a result, which provides the proof-of-concept verification of a viable high speed VLC link.
