Promising Materials Emerge for Next-Gen LED-Based Data Communications

A team of researchers has examined how organic semiconductors, colloidal quantum dots (CQDs), and metal halide perovskites can be used in high-speed LED-based optical communication systems. LED-based techniques enable computing devices to communicate with one another by using infrared light. However, LED techniques aren’t often used. In their current state, LEDs transmit data at far slower speeds compared to other wireless technologies such as light-fidelity (Li-Fi). The team explored efforts to improve the performance and efficiency of these LEDs with consideration of their potential applications in on-chip interconnects and Li-Fi.
