PHY2034 Lasers, Materials and Nanoscale Probes for Quantum Applications 2018-19
Dr A.S. Plaut
Delivery Weeks: T2:01-11
Level: 5 (NQF)
Credits: 15 NICATS / 7.5 ECTS
Enrolment: 8 students (approx)


We are living in the age of quantum optoelectronics: optical-signal processing, high-power laser sources, optical amplifiers, single-photon manipulation, quantum confined-electron devices, etc.. This module will emphasize how our understanding of light and matter may be used to provide assorted optoelectronic devices, and also how they in turn may enhance our understanding of light and matter.

Module Aims

This module pre-dates the current template; refer to the description above and the following ILO sections.
