Vector Photonics

Vector Photonics’ PCSELs are the first, major break-through in semiconductor laser technology for 30 years. The company is a spin-out from one of the world’s leading academic groups in Photonics at the University of Glasgow. Its proprietary technology, developed since 2012, places Vector Photonics at the heart of the rapidly growing datacenter industry. PCSELs (Photonic Crystal Surface Emitting Lasers) are low cost, robust with high speed and power. This combination of key characteristics gives them a huge advantage over present-day, commonly used VCSELs (Vertical Cavity Surface Emitting Lasers), which compromise wavelength range and power, and EEL lasers (Edge Emitting Lasers), which are high-cost and fragile. PCSELs have other advantages too. They emit light from the top surface, like VCSELs, making them easy to package and incorporate into PCBs and electronic assemblies. They are also made in a similar way to EELs, so existing, experienced, supply chain capability and capacity can be utilised.
