CST Global Leads Research for Next-Gen GaN Laser Technology

Posted Apr 21, 2017 by

Compound Semiconductor Technologies Global (CST Global) along with its academic partners Glasgow and Aston Universities has decided to commercially lead the government-funded, CoolBlue research project. The project, ‘Quantum Cooling using Mode Controlled Blue Lasers’ is funded by the premier UK government research funding agency for engineering and the physical sciences, the Engineering and Physical Sciences Research Council (EPSRC). The EPSRC is expected to invest around £800m per year in both research and postgraduate training.

The CoolBlue project starts in April 2017 and will last 14 months. It seeks to develop next generation GaN laser technology for use in atomic-cooled, quantum sensors as traditional laser sources have proven too complex and inefficient to produce commercially, in this application. However, direct blue laser diode sources offer increased power and simplicity, with the opportunity to miniaturize quantum sensor formats and produce them in a robust format. 

The CoolBlue project funds two cycles of laser design, fabrication and test, which will be done at CST Global, optimizing key laser parameters, including power.

The knowledge and expertise generated during the project will allow CST Global to develop new products for the emerging GaN laser markets. It expects to re-invest the further additional revenues in other aligned research projects. Commercialization of academic research by the Universities of Glasgow and Aston should also have a positive impact on further, similar, research opportunities and funding.
