By combining adiabatic optical coupling, silicon-based feedback and cavity engineering, and ultra-compact laser concepts, CEA ...

The quest is on to make terahertz sources that are small, portable and capable of operating at room temperature. Such a breakthrough could lead to advances in everything from cancer screening to ...

Terahertz quantum cascade lasers (QCLs) represent a transformative development in the field of terahertz photonics, providing coherent radiation within a traditionally challenging spectral region ...

Biomass can be converted into valuable gases. But in order to control this process, the amount of water vapor has to be measured. This is notoriously hard, because other components of the gas can ...
