Heriot-Watt UniversityХs Institute of Photonics and Quantum Sciences (IPaQS) is a leading UK centre for advanced photonics, quantum science and engineering. Our activities span ultrafast nonlinear optics, time-varying photonics, epsilon-near-zero (ENZ) and low-index materials, integrated photonic systems, and quantum lightРmatter interactions. Core technical strengths include femtosecond pumpРprobe spectroscopy, nonlinear optical characterisation, thin-film ENZ material platforms (e.g. TCOs), photonic device design and nanofabrication, and AI-assisted optimisation of optical systems. We combine fundamental materials science with system-level photonic integration, enabling dynamic control of light in time and space for applications in quantum technologies, optical neural networks, deep-UV generation, and advanced sensing. Our unique value lies in translating extreme ultrafast nonlinearities into programmable photonic functionality, supported by a strong IP portfolio and active industrial engagement. The Institute is strategically positioned within the UKХs critical technologies landscape in quantum, advanced materials, semiconductors, and next-generation computing platforms.
