Terahertz room-temperature integrated parametric source

Terahertz room-temperature integrated parametric source

This project will demonstrate a radically new continuous-wave, electrically pumped terahertz emitter. Compared to existing THz sources, the TREASURE source will bring together several crucial advantages that are far from being simultaneously available in any existing source today: compact size, room-temperature operation, output power scalable up to the microwatt range, custom emission frequency from...

Concept and project objective(s) The TREASURE project will demonstrate an integrated terahertz (THz) emitter at room temperature, based on a parametric optical process in an AlGaAs device, combining strong material nonlinearity and high optical confinement. The approach followed is based on a quasi-phasematching scheme in the whispering-gallery cavity of

Industry / Innovation

Potential impact The device concept developed within TREASURE will open new perspectives for various THz technological applications, mainly due to the compact and rugged form of the device, to its low-power consumption, and to its room-temperature operation. The expected level of performances is unprecedented both in and outside Europe. Moreover the device is scalable, in...
