A significant advancement in thin film technology has the potential to enhance the sensitivity of gravitational wave detectors, facilitating a deeper understanding of the universe. The new technique was developed at UWS’s Institute of Thin Films, Sensors and Imaging and involves producing thin films with reduced thermal noise, improving their detection capacity.
Researchers have developed a thin film technology that enhances gravitational wave detector sensitivity. This breakthrough promises to deepen our understanding of the universe, expanding the detection range of cosmic events, and could benefit high-precision devices like atomic clocks and quantum computers.
New frontiers in the study of the universe – and gravitational waves – have been opened up following a breakthrough by University of the West of Scotland (UWS) researchers.
The groundbreaking development in thin film technology promises to enhance the sensitivity of current and future gravitational wave detectors. Developed by academics at UWS’s Institute of Thin Films, Sensors and Imaging (ITFSI), the innovation could enhance the understanding of the nature of the universe.
Gravitational waves, first predicted by Albert Einstein’s theory of general relativity, are ripples in the fabric of spacetime caused by the most energetic events in the cosmos, such as black hole mergers and neutron star collisions. Detecting and studying these waves provides invaluable insights into the fundamental nature of the universe.
Dr. Carlos Garcia Nuñez, Senior Lecturer at School of Computing, Engineering and Physical Sciences (CEPS), said: “At the Institute of Thin Films, Sensors and Imaging, we are working hard to push the limits of thin film materials, exploring new techniques to deposit them, controlling their properties in order to match the requirements of current and future sensing technology for the detection of gravitational waves.”
“The development of high reflecting mirrors with low thermal noise opens a wide range of applications, which covers from the detection of gravitational waves from cosmological events to the development of quantum computers.”
The technique used in this work — originally developed and patented by Professor Des Gibson, Director of UWS’s Institute of Thin Films, Sensors and Imaging – could enable the production of thin films that achieve low levels of “thermal noise”. The reduction of this kind of noise in mirror coatings is essential to increase the sensitivity of current gravitational wave detectors – allowing the detection of a wider range of cosmological events — and could be deployed to enhance other high-precision devices, such as atomic clocks or quantum computers.
Professor Gibson said: “We are thrilled to unveil this cutting-edge thin film technology for gravitational wave detection. This breakthrough represents a significant step forward in our ability to explore the universe and unlock its secrets through the study of gravitational waves. We believe this advancement will accelerate scientific progress in this field and open up new avenues for discovery.”

The development of coatings with low thermal noise will not only make future generations of gravitational wave detectors more precise and sensitive to cosmic events, but will also provide new solutions to atomic clocks and quantum mechanics, both highly relevant for the United Nations’ Sustainable Development Goals 7, 9 and 11.
