Photons and Matter
(formerly Optoelectronics)
The group operates at the cusp between fundamental physics and development of device concepts though measurements of fundamental optical processes in semiconductor structures, enabling advances in understanding of light-matter interactions, verification of theories, and development of new device concepts, particularly by integration of functions. The group activity originally based on the physics of gain and recombination in quantum confined structures now embraces colloidal dots and collaborations with bioscience. Currently interrelated themes include Biophotonics, Integrated Optoelectronics, Nanophotonics, and the physics of ensembles of quantum dots and of individual dots and their environment (colloidal and epitaxial). These developments are supported by a new MSc in Biophotonics.
