Atlanta, GA — USA

Come and meet the Avicena team at SC24 (booth 4634) to experience the latest advances in interconnect technology.

LightCounting featured Avicena in their Highlights from Supercompute 24:

“Avicena showcased at SC23 its tiny 1Tb/s optical transceiver chip based on the company’s microLED technology. The LightBundle ASIC measures 3mm x 4mm and supports a reach of up to 10m, ideal for chip-to-chip and inter-rack communications. The LED-based interface can operate at temperatures up to 150OC. The gallium nitride microLEDs are integrated directly onto a CMOS IC. Each microLED array is connected via a multi-core fiber cable to corresponding photodetectors. Avicena ASIC supports 331 lanes, each at 4Gb/s, for a total bandwidth exceeding 1Tb/s. However, its next generation design will support 1.6Tb/s which will also be used for an AOC product. The ASIC includes electrical circuitry for the optical transmitter and receiver arrays.

At SC24 Avicena showed its technology including mockups of how its LightBundle ASIC could be placed on a board next to a GPU, and how it could be embedded as a chiplet with the GPU, see Figure 10. Avicena is developing an active optical cable using its technology and is looking to prove its technology for an on-board optics design first before advancing to a co-packaged design. Also shown was a 4,000 50-micron fiber bundle that would support up to 12.8Tb/s throughput.”
