£6.5 million programme brings together world experts in terahertz research

Researchers at the University of Leeds are to benefit from a £6.5 million programme into terahertz lasers with applications ranging from security to future quantum computers.

The programme, funded by the Engineering and Physical Sciences Research Council (EPSRC), will involve researchers from the School of Electronic and Electrical Engineering, University of Leeds; the Department of Electronic and Electrical Engineering, UCL; the London Centre for Nanotechnology; and the Cavendish Laboratory, University of Cambridge.

The terahertz (THz) frequency region is the last unexploited part of the electromagnetic spectrum.

Lying between radio and optical frequencies, the bandwidth available is some 30 times greater than the entire allocated radio spectrum.

The main reason why this resource has been so little used is the complexity, bulk, high power consumption and lack of coherence of current THz technologies.

The programme will bring together the world leading teams that have pioneered THz quantum cascade lasers, microwave photonics and THz quantum state control to open up the THz spectrum for widespread scientific and commercial application, through the use for the first time of photonics-enabled coherent techniques.
