Abstract

With the development of Internet of Things (IoT) technology, there is an increasing demand for integrated optoelectronic systems. Multiple quantum well (MQW) diodes can transmit and receive information through visible light, serving as both light-emitting diodes (LEDs) and photodetectors. Furthermore, the overlap of emission-detection spectra in III-nitride MQW diodes provides an interesting capability of detecting and modulating their own emitted light. In this study, we have experimentally demonstrated the coexistence of emission-detection in III-nitride MQW diodes and established an optical-based wireless audio communication system. When the bias voltage is greater than the turn-on voltage and the device is simultaneously illuminated, III-nitride MQW diodes can achieve both light emission and detection. This work paves the way for developing versatile III-nitride MQW diodes for device-to-device data communication in smart displays.
