Ficai, AUO, and Dingyuan cooperate to launch Micro LED high-speed optical interconnection solution

Recently, Fucai demonstrated an optical I/O solution based on Micro LED, which was jointly developed by Fucai, AU Optronics and Dingyuan Optoelectronics, and was jointly exhibited at Touch TaNvan2026.

Among them, Fucai provides core GaN-based Micro LED light source chips, which adopt GemiLED™ dual-emitting layer structure, with a single channel modulation rate of 1.25Gbps, and can be multi-channel parallel expanded to 800G/1.6T+ bandwidth. Compared with the traditional VCSEL solution, the power consumption is reduced by about 95%, and it can operate stably at a high temperature of 125°C.

Dingyuan Optoelectronics is responsible for matching Micro-PD micro photodetector arrays with Micro LED pixel-level precision to achieve high-speed, low-noise optical signal reception.

AU Optronics is responsible for the design and system integration of CPO co-packaged optical modules. Through optical waveguide and microlens coupling technology, it integrates optical transceiver components and ASIC driver circuits at the chip level to create high-density, low-latency short-distance optical interconnect modules.

It is understood that this solution is oriented to ultra-short-distance high-speed interconnection (

At present, Fucai has successfully demonstrated single-channel 1.25 Gbps performance based on Micro LED, and will continue to improve modulation speed and reliability through continuous cooperative development with system partners. Fucai said that key component verification has been completed and 800G module system verification will be promoted in 2026. Fucai also demonstrated two other optical systems based on VCSEL and CW-DFB LD I/O solutions.

AU Optronics also stated that it plans to commercialize optical I/O solutions based on MicroLEDs within 2-3 years.

With the explosion of AI computing power, Micro LED CPO has become a trend and is regarded as a core candidate for the next generation CPO technology due to its three major advantages: extremely low power consumption, ultra-high bandwidth density, and excellent temperature stability.
