Our terahertz quantum cascade laser (THz-QCL) device establishes a world record

Monday, November 2, 2020

Scanning electron microscope image of a terahertz quantum cascade laser device.In collaboration with Professor Qing Hu's research group from the Massachusetts Institute of Technology (MIT) in the USA, our research team recently demonstrated terahertz quantum cascade lasers (THz QCLs) that established a world record for high-temperature operation. Moreover, the portable size of this QCL device now makes the generation of high-power terahertz radiation outside of a laboratory environment possible.

This work is reported in Nature Photonics.

"Many authorities in the field didn't believe these devices could work outside a laboratory environment or anywhere close to room temperature," said Professor Zbig Wasilewski and as commented by Professor Qing Hu from MIT,

With a high operating temperature, we can finally put this in a compact portable system and take this breakthrough technology out of the laboratory.
