Vector Photonics, a spin-out company from the University of Glasgow, will begin commercialisation of an uncooled, 1 Watt, 1310nm, CW PCSEL. The datacoms PCSEL is for the interconnects, silicon photonics and CPO used in next-generation, cloud datacentre applications. A 1-Watt laser offers significant, optical power increases over incumbent DFB technology, with countless manufacturing and energy saving benefits. The 1 Watt laser leverages Vector Photonics’ existing PCSEL commercialisation work.
Dr. Richard Taylor, CTO of Vector Photonics, said, “An uncooled, 1 Watt PCSEL is a game-changer for cloud datacoms applications. Currently, next-generation datacentre interconnects must deliver 800Gbps, increasing to 1.6 Tbps and then 3.2 Tbps over the next decade. The 1 Watt PCSEL enables this development, with a significant reduction in the quantity of lasers required over DFB technology. The interconnects, silicon-photonics chips and CPO systems, where they are used, become significantly easier to make, with the likelihood of improved yield and reliability. In addition, the 1 Watt PCSEL has a symmetrical far-field which requires less operational power to achieve the necessary performance.
“The full impact of a 1 Watt PCSEL is yet to be quantified. However, these high-power lasers will change the entire architecture of datacoms chips and systems. Further, significant benefits include reduced power consumption, heat, latency, and manufacturing costs.”
About Vector Photonics
Vector Photonics produces PCSEL-based, III-V semiconductor lasers – the most significant innovation in laser design and manufacture for 30 years. The company is a spin-out company from the University of Glasgow; one of the UK and world’s Optical and Photonics centres of excellence. PCSELs (Photonic Crystal Surface-Emitting Lasers) are low cost, robust, have a broad wavelength range and high power. This is a unique combination of key characteristics which gives them a huge advantage over all other current, semiconductor laser technologies.
