DESCRIPTION – summary of the module content (100 words)

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 – intentions of the module
