Paper Abstract

The multifunctional technology is essential for the Internet of things in which a single device can have multifunctionalities for the development of monolithic multicomponent system. GaN photonics provides a great potential to integrate photonic and electronic circuits on a single chip for modern computing system architecture. When appropriately biased, multiple quantum well (MQW) diode intrinsically exhibits the simultaneous emission-detection phenomenon because there is a spectral overlap between the electroluminescence spectra and photocurrent responsivity spectra. We come up with the Wang effect to make a fundamental interpretation of the intriguing phenomenon, and experimentally demonstrate full-duplex audio communication using the dual-functioning MQW-diode, which can simultaneously transmit and receive information using visible light.
