Project description

The quantum cascade laser is an intersubband laser fabricated by a sophisticated high vacuum semiconductor growth technique called molecular beam epitaxy. The lasers comprise a carefully designed layered superlattice structure, containing thousands of semiconductor layers, each of nanometre-scale thickness and each deposited with an atomic layer resolution. The terahertz quantum cascade laser was highlighted by the journal Nature Photonics as one of the top photonics breakthroughs in the last 50 years, and the Leeds group is internationally recognized to be leading in the growth and fabrication of these lasers, often working with international collaborators. This PhD project will optimize the growth of quantum cascade lasers to increase their output power, operating frequency range, frequency tuneability, and maximum operating temperature. It will also explore new materials systems for use as quantum cascade lasers and detectors, and for developing understanding of the physical properties of intersubband and heterostructure devices.
