Avicena, the leader in next-generation microLED interconnects, today announced a major milestone at ECOC 2025 with a live demonstration of a fully operational microLED-based optical link operating at an industry-leading Tx power of 200 femtojoules per bit (fJ/bit) at <1E-12 raw bit error rate (i.e. no forward error correction). This achievement highlights the efficiency of Avicena's scalable LightBundle platform for high-performance computing and AI data centers.

Using a high-sensitivity receiver, modified from a high-volume foundry camera sensor process, the demonstration link operates at dramatically reduced microLED drive currents. Since LEDs do not require the threshold current typical of lasers, they run fast even at low currents. In this live demonstration, the LED operates at about 0.25mA drive current and 4 Gb/s and is paired with a hybrid-bonded camera sensor and discrete TIA.
