As Covesion’s products are so well documented, we were able to easily select the waveguide we needed and discussions with Covesion’s team were helpful and clear. The product works well and is used regularly by the team here at IDQ.

The cooperation with our partners Covesion and Fraunhofer IPM during the project and beyond was excellent. It enabled us to achieve results beyond the planned objectives.

The customer service from Covesion has always been excellent. We have a great rapport with Corin (ProfessorCorin Gawith, CTO, Covesion) and the team, and their knowledge is invaluable. I have had occasion to use Covesion crystals twice during my research at The University of Glasgow and the turnaround for the custom products was very quick, meaning the research could continue without delay.
Specifically with regards to our area of interest, the PPLN crystals are periodically poled, and the period of poling needs to be optimised to ensure the best performance of the source, enhancing the efficiency of the generation. Covesion gave us various options rather than just one specific period for the poling. For example, in one of the devices there were different groups of poling periods and that allowed us to optimise for best performance and find the configuration that worked the best.
