CTT may seem like a "new kid on the block", but it was founded by people who have been involved in research for decades, and their names will be familiar to many in the global terahertz community. The company was incorporated in 2022 by senior astronomy instrumentation academics from the School Of Physics and Astronomy at Cardiff University.

CTT was created to commercialise unique technology resulting from more than five decades of pioneering work. The activity was initiated by Professor Peter Ade at Queen Mary College, London (now QMUL) and continued in the 21st century at Cardiff University.

In the 1970s Peter invented and then meticulously refined a multi-layer metal mesh solution to frequency selection which makes possible unparalleled control of band definition and very high attenuation of out-of-band radiation over a broad range of frequencies.

This therefore became an enabling technology for astronomical receivers starting with cryogenic instruments on UKIRT and JCMT in the 1970s. Our CEO, Professor Carole Tucker has worked closely with Peter and has managed filter production since the 1990s.

Mission Statement

To deliver best-in-class precision-engineered products and the innovation required to meet the future global demands for terahertz technology.

Vision Statement

To play a leading role in advancing terahertz science, driving innovations that shape the future of technology and discovery.

The academic research group went on to contribute to IRAS, ISO, and most notably ESA's Herschel, and Planck Space Observatories. The metal mesh filter technology is now being built into the next generation of terrestrial and space based projects such as the Simons Observatory and PRIMA (the PRobe far-Infrared Mission for Astrophysics), a candidate NASA probe class mission.

Our technology also underpins the recent proliferation of activity in the terahertz region of the electro-magnetic spectrum and will play an important role in the development of sources, receivers, short range communications, plasma diagnostics, climate monitoring and security screening.

So far thousands of precision-engineered devices have been constructed, helping to shape the evolution of terahertz technology worldwide.

The design, manufacture and test phases of this technology are assembled under a commercial umbrella for the first time through Celtic Terahertz Technology Ltd. We are building a dedicated facility at our Cardiff home to generate greater production capacity along with improved performance, quality and reliability in the finished product.

Meet the people behind these extraordinary innovations.
