| Description | The research undertaken on this grant has provided new information about the performance of quantum cascade lasers based upon InP. Such devices are important for applications in environmental sensing. A particular issue with quantum cascade lasers is that they require cooling to operate. This is expensive and in many cases impractical. This research helped to show the causes of this sensitivity and helped to further develop optimum designs of these devices. |
| Exploitation Route | The results of the work will inform the future development of quantum cascade lasers. |
| Sectors | Aerospace Defence and Marine Agriculture Food and Drink Chemicals Education Manufacturing including Industrial Biotechology Pharmaceuticals and Medical Biotechnology |
| Description | At this stage, the findings have mainly been disseminated to the scientific community working on quantum cascade lasers. |
