Articles from Avicena

Avicena, the leader in next-generation microLED interconnects, today announced a major milestone at SuperCompute 2025 (SC25): its LightBundleTM microLED-based links now operate at 4Gbps per lane with transmitter currents as low as 100µA per LED. At this current, each link closes at a raw BER of 1x10-12 with an equivalent energy of 80fJ/bit per LED, all without Forward Error Correction (FEC). This achievement highlights the LightBundle platform’s ability to deliver the world’s lowest-power optical interconnects for next generation AI infrastructure by addressing the increasing bandwidth, distance, and reliability requirements most efficiently.

Avicena, the leader in ultra-low power high-density microLED-based interconnects, announced today that Marco Chisari, former Executive Vice President, Head of Samsung Foundries and Head of the Samsung Semiconductor Innovation Center (SSIC), has joined Avicena as the Chief Executive Officer (CEO) and a member of the board of directors (Board). Marco succeeds co-founder and CEO Bardia Pezeshki, who will assume the role of Chief Technology Officer (CTO).

Avicena, headquartered in Sunnyvale, CA, announced today that the company will work with TSMC to optimize photodetector (PD) arrays for Avicena’s revolutionary LightBundle microLED-based interconnects. LightBundle supports > 1Tbps/mm shoreline density and extends ultra-high density die-to-die (D2D) connections to > 10 meters at class-leading sub-pJ/bit energy efficiency. This will enable AI scale-up networks to support large clusters of GPUs across multiple racks, eliminating reach limitations of current copper interconnects while drastically reducing power consumption.

Avicena, provider of advanced LED based optical interconnects for computing, today announced the appointment of Greg Dougherty to its board of directors, effective immediately. Mr. Dougherty brings to the board a proven track record of executive leadership and extensive experience in the optical communications industry, along with strong operational expertise in the development of innovative optical products and technologies.

Avicena, a privately held company headquartered in Sunnyvale, CA, is demonstrating the world’s highest temperature optical link operating at up to 235°C using its LightBundleTM communication architecture and technology at the Optical Fiber Communication Conference (OFC) 2023 in San Diego, CA (https://www.ofcconference.org/en-us/home/). The Avicena LightBundle architecture breaks new ground by unlocking the performance of xPUs, memory and sensors, removing key bandwidth and proximity constraints while simultaneously offering an order-of-magnitude reduction in power consumption.

Avicena, the leader in high-performance microLED-based chip-to-chip interconnects, today announced that it has completed the acquisition of a microLED fabrication facility and associated engineering team from Nanosys. This transaction significantly enhances Avicena’s capabilities in the development and manufacturing of high-speed GaN microLEDs optimized for parallel multi-Tbps interconnects.

Avicena, a privately held company in Mountain View, CA, is demonstrating its LightBundleTM multi-Tbps chip-to-chip interconnect technology at the European Conference for Optical Communications (ECOC) 2022 in Basel, Switzerland (https://www.ecocexhibition.com/).
