Micro-LED optical interconnect know-how grew to become the focus on the 2026 CIOE (China Worldwide Optoelectronics Expo).
A variety of ecosystem members, from epitaxy, chip, and show module suppliers reminiscent of Enkris Semiconductor, LEKIN, Starksemi, and Raysolve, to system structure distributors reminiscent of Nexilumen (Shanghai) and Intelligence Computing Optical Interconnects (an affiliate of Wuhu Token Science), showcased their newest breakthroughs in micro-LED optical interconnect options.
From an architectural perspective, these corporations change conventional semiconductor lasers with micro-LED arrays as gentle sources and leverage dense multichannel parallel transmission to attain ultra-high bandwidth densities. The general energy consumption of those options is often focused to be lower than 1 to 2 pJ/bit. This can be a dramatic discount in comparison with conventional optical engine designs.
Mixed with wafer-level manufacturing and CMOS-compatible processes, this know-how presents a viable path towards low-cost, high-volume manufacturing. Micro LED optical interconnects are shifting from proof-of-concept to industrial deployment as AI computing calls for quickly increase and short-range interconnects attain bodily bandwidth bottlenecks.
Raysolve
Raysolve has demonstrated a micro-LED optical interconnect validation platform co-developed with companions to allow multi-core fiber (MCF) sign transmission. Constructing on know-how analysis initiated at HKUST in 2021, the corporate has expanded past microdisplays to handle vital optical interconnect metrics reminiscent of gentle supply modulation pace, excessive effectivity collimation, and low crosstalk.
Raysolve is at the moment working with main optical interconnect and transceiver module distributors to advance purposeful validation, efficiency optimization, and end-market utility testing.
stark cicada
Starksemi exhibited a micro-LED optical interconnect structure designed for high-speed photonic hyperlinks. The corporate has demonstrated a high-bandwidth micro-LED that achieves -3dB bandwidth of roughly 2,500 MHz, considerably exceeding customary micro-LEDs (~500 MHz).
This structure is predicted to scale back power consumption by as much as 20x by using dense parallel channels. Starksemi has begun delivery samples to strategic companions for product validation.
Wrekin
In parallel with the dwell demonstration of GaN-on-Si micro LED optical interconnect wafers, LEKIN exhibited a whole micro LED optical interconnect answer primarily based on the GaN-on-Si platform. This answer has three main advantages:
-
Excessive Bandwidth: Designed to satisfy the necessities of 800G and 1.6T optical transceiver modules.
-
Extremely-low energy: Vitality consumption is 1-2 pJ/bit, considerably decrease than conventional laser engines.
-
Thermal stability: -40°C to 125°C working temperature vary
Encris
Enkris has launched an 8- to 12-inch GaN-on-Si micro-LED gentle supply personalized for optical communications. Working at a present density of 500 A/cm2, the gadget achieves a bandwidth of 1.6 GHz whereas consuming lower than 1 pJ/bit.
As {industry} consideration shifts to high-speed seen gentle communications (VLC), Encris leverages its large-diameter GaN-on-Si epitaxy capabilities to serve the optical communications area.
nexi lumen
Nexilumen exhibited a prototype pattern of its high-performance micro-LED optical interconnect system developed in-house.
Lengthy-wavelength InGaN micro-LED: achieved emitter power effectivity of 0.056 pJ/bit, electro-optic modulation bandwidth of two.85 GHz, and steady 1.5 Gbps knowledge transmission at a low present density of 6.25 A/cm2.
Brief wavelength micro-LED: 405 nm variant maintains a bandwidth of >3 GHz over your complete present vary and a excessive frequency response of >3 GHz at each low (3.2 mA) and excessive (32 mA) drive currents.
The engineering group is at the moment integrating CMOS driver circuits and micro-LED arrays by monolithic and heterogeneous integration, and plans to construct a prototype 1.6 Tbps optical interconnect system within the close to future.
Intelligence Computing Optical Interconnect
Intelligence Computing Optical Interconnects, in collaboration with shareholder Wuhu Token Sciences, has demonstrated a short-range, high-speed micro-LED optical interconnect hyperlink focusing on an total end-to-end power effectivity of lower than 1 pJ/bit. Lightlink has initiated an industry-academia analysis collaboration to advance technical validation and commercialization.
Business outlook
Pushed by excessive market expectations, micro-LED optical interconnects are gaining consideration all through the provision chain. In line with TrendForce, micro-LED-based co-packaged optical (CPO) transceiver modules might enter mass manufacturing as early because the second half of 2028, with market manufacturing worth anticipated to achieve roughly USD 848 million by 2030.
