Vector Photonics commercilising uncooled 1W 1,310nm CW PCSEL for datacoms
Vector Photonics is beginning commercialisation of an uncooled, 1W, 1,310nm, CW PCSEL. The PCSEL is intended for the interconnects, silicon photonics and CPO used in next-generation cloud data centre applications. A 1W laser offers significant optical power increases over incumbent DFB technology, with countless manufacturing and energy saving benefits. According to the firm, this will be a ‘game-changer’ for cloud datacoms applications.
Currently, next-generation datacentre interconnects must deliver 800Gbps, increasing to 1.6Tbps and then 3.2Tbps over the next decade. The 1W 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 1W PCSEL has a symmetrical far-field that requires less operational power to achieve the necessary performance.
The full impact of a 1W PCSEL is yet to be quantified, according to Vector Photonics. However, the firm says that such 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.
