“…Quantum well (QW) diodes that inherently exhibit multifunctionalities of light emission, detection, modulation, and energy harvesting have great potential for the development of monolithic optoelectronic systems. − In particular, their emission spectra partially overlap with their responsivity spectra due to the same QW active region, and thus, the QW diode is able to detect, modulate, and harvest the light emitted by itself. , By using the same fabrication process flow, we can monolithically integrate different QW diodes into a single chip, − in which all these components share identical QW structures. Zhang et al demonstrated a monolithic GaN optoelectronic system consisting of a transmitter, a waveguide, a beam splitter, receivers, and a monitor, in which light emission, propagation, and detection can be manipulated, and data communication among them is realized through photons.…”

A simultaneous emission-detection phenomenon occurs when a quantum well (QW) diode is biased with a forward voltage and illuminated with a shorterwavelength light beam. The diode is able to detect and modulate light emitted by itself due to its spectral emission-detection overlap. Here, two identical QW diode units separately function as a transmitter and a receiver to establish a wireless light communication system. In association with energy diagram theory, we explain the irreversibility between light emission and light excitation in the QW diode, which may help us deeply understand various expressions in nature.

Dual-functioning multiple quantum well (MQW) diodes can simultaneously transmit and receive information through visible light. Here, we report vertically stacked red, green, and blue (RGB) MQW diodes for light detection and display applications. Both blue and green MQW diodes are monolithically integrated with distributed Bragg reflector (DBR) filters to realize the separation of light. The versatile RGB MQW transmitter/receiver system not only creates full-color display but also effectively separates RGB light into various colors. These results open feasible routes to generate multifunctional device for the development of full-color display and light receiver.
