Dual-Color Micro-LED Transmitter for Visible Light Communication

Abstract

We report the integration of blue micro-LED onto to the substrate of green micro-LED, by transfer printing. This dual color device fabrication and performance as a visible light communication transmitter is demonstrated.

Underwater Wireless Optical Communications at 100 Mb/s using Integrated Dual-Color Micro-LEDs

“…Blue-violet and blue-green micro-LED arrays were fabricated by TP a blue-micro-LED platelet onto the substrate of the violet and green micro-LED, respectively. The blueviolet array follows the same fabrication process as the bluegreen array which is discussed in detail in [5].…”

“…An elastomeric stamp was used to pickup the blue micro-LED platelets from their Si substrate and print them onto the pre-prepared green and violet sapphire substrate micro-LED chips. The blue micro-LED platelet was then electrically insulated by parylene-C and addressed by Ti/Au (50/200 nm) metal tracks, following the process described in [5]. Fig.…”

Investigation of Electrical Properties and Reliability of GaN-Based Micro-LEDs

“…Many research works have already made efforts to optimize these devices. In some research into Micro-LEDs, the pixel size was quite large, with a pixel pitch of hundreds of micrometers, and a current density of only several tens of A/cm 2 , due to immature technology [12,13]. Micro-LEDs grown on Si substrate were once regarded as mainstream, due to the compatibility with the existing manufacturing process.…”

Optical dynamics at the MoO3/ZnPc interfaces prepared for visible light communications

“…In the recent years, visible light communications (VLC) technology gained interest due to the need for high transfer rates. Such systems can transmit signals with a rate up to 500-800 Mbit/s [1,2]. The performance of these systems is mainly based on the emitters and receivers.…”
