University of Michigan in the USA has claimed the highest external quantum efficiency (EQE) and smallest linewidth so far for red-emitting indium gallium nitride (InGaN) micro-LEDs, using photonic crystal (PhC) structures [Yuanpeng Wu et al, Light: Science & Applications v15, p133, 2026] Further, the emission wavelength was stable for a wide range of injection currents. The 5nm full-width at half maximum (FWHM) was about one order of magnitude narrower than previously reported values. The researchers see narrow linewidths as “paramount for achievin...

AI is pushing the boundaries of computing infrastructure to new levels as data centers scale to millions of GPUs. High-speed interconnects play a critical role in enabling this expansion with high-throughput and reliable data movement between compute, memory, and storage systems. New photonic connectivity technologies are emerging to meet the higher bandwidth requirements of GPU-dense architectures. Credo is innovating across its product portfolio that spans diverse physical mediums, distances, and protocols to meet customer needs. Credo began investing in microLED technolo...
