Vector Photonics is at the forefront of new and developing, laser technologies. Our strategy is to continue to develop our PCSEL technology to improve manufacturing techniques and broaden the range of applications using PCSELs. Our initial focus is on datacoms for Datacenter applications, validating the commercial use of our technology. Our future plans include developments for LiDAR, optical coms, mobile consumer and sensing markets where PCSEL technology offers breakthrough performance and costs.

Dr. David Childs presents his Paper on the first speed measurement of a PCSEL (Photonic Crystal Surface Emitting Laser), clearly demonstrating that the PCSEL’s speed aligns with the company’s device modelling. These results verify that Vector Photonics PCSEL technology is capable of significantly faster speeds than equivalent VCSEL or EEL’s.

David goes on to conclude that a PCSEL, with a smaller area and optimised for speed, has the potential to be over two times faster than a VCSEL equivalent and three times faster than a DFB laser equivalent.

Dr. Richard Taylor, CTO at Vector Photonics, explains the company’s unique PCSEL technology, its benefits, and why it will revolutionise semiconductor laser manufacture in future.


Vector Photonics’ technology is protected by two, key patents, based on the research of three of its founding members Dr. Richard Taylor, Dr. David Childs and Prof. Richard Hogg. The patents are licensed to Vector Photonics by the University of Glasgow on an exclusive, worldwide basis with the right to sublicence.

Vector Photonics expects to file several more patents as PCSEL technology is developed for volume production.
