Vector Photonics develops a new class of semiconductor lasers

Vector Photonics, a spin-out from the University of Glasgow, announced plans to commercialize a new class of Photonic Crystal Surface Emitting Lasers (PCSEL) technology for hyperscale data center applications. The technology uses a 2D grating structure to scatter light linearly and orthogonally.

Vector Photonics CEO, Neil Martin, said, “PCSELs are low cost, robust, have a broad wavelength range and high power. This combination of key characteristics gives them a huge advantage over most of the laser technologies used today. This includes VCSELs (Vertical Cavity Surface Emitting Lasers), which are robust, but compromise wavelength range and power, and EEL’s (Edge Emitting Lasers), which have broad wavelength range, but are expensive to make and are fragile to handle.

“PCSELs emit light from their top surface, like VCSELs, making them easy to package and incorporate into PCBs and electronic assemblies. They are also produced in a similar way to EELs, allowing us to draw on existing supply chain expertise and capacity as we grow.”
