This PhD project explores the use of integrated quantum technologies to revolutionize optical sensing in marine environments. Light plays a critical role in ocean processes such as warming, photosynthesis, and animal behavior, yet monitoring these processes is challenging due to the harsh conditions of the ocean. Optical sensing, particularly when paired with autonomous platforms, offers a promising solution.
The project will develop and demonstrate quantum-enabled sensors with three key innovations:
-
Ultra-High Dynamic Range Irradiance Sensors
Using solid-state detectors, the project will create sensors capable of measuring underwater light fields across extreme lighting conditions—from bright daylight to the darkness of abyssal depths. These sensors will seamlessly transition between conventional and photon-counting modes, enabling global-scale monitoring of biologically relevant light signals. -
Quantum LIDAR Enhancements
The same high dynamic range sensors will improve quantum LIDAR systems by extending sensitivity to both distant, weak signals and intense, near-field signals. This dual capability is crucial for ecological studies in turbid waters where light attenuation is significant. -
Single-Photon Spectroscopic Sensors
Leveraging the precision of single-photon detection, the project will develop spectroscopic tools to distinguish Raman and other inelastic scattering signals. These tools will enable accurate identification of particle composition, including organic matter, microplastics, and oil droplets.
The student will work in collaboration with Fraunhofer UK and the Marine Optics and Remote Sensing group at the University of Strathclyde, gaining hands-on experience in quantum photonics and oceanographic fieldwork. This interdisciplinary project offers a unique opportunity to contribute to environmental science through cutting-edge quantum technology.
