Telecom spectrometers

Vancouver, British Columbia, based T-Ray Science has entered into a research collaboration with Leeds University to develop pulsed and continuous-wave (CW), fibre-coupled terahertz (THz) spectrometers that operate at telecom wavelengths.

Prof Edmund Linfield will lead the project in the School of Electronic and Electrical Engineering, with Dr John Cunningham and Prof Giles Davies.

The commercial advantage of developing a spectrometer at the telecom wavelength is that the researchers will be able to use mass-produced telecom components such as lasers, fibres and couplers that could reduce the cost of a system by 90 per cent compared to existing THz systems.

’The collaboration with Leeds University could lead to low-cost, compact and easy-to-use terahertz diagnostic and imaging systems for applications in medical imaging, explosives detection, airport security and manufacturing quality control,’ said Thomas Braun, president and chief executive of T-Ray Science.

The Leeds researchers have also received a grant from the Engineering and Physical Sciences Research Council to fund their work on the project.

T-Ray supported the grant application and will assist in the project through laboratory tests of the newly developed system. The company will also have the opportunity to license any Intellectual Property that may result from the project.

T-Ray owns the exclusive licence from the Massachusetts Institute of Technology for the only known CW coherent detection system, which was invented by Dr Simon Verghese and Dr Alex McIntosh.
