Optical switching using quantum dot-micropillar cavities
In this thesis we use optical spectroscopy to investigate III/V semiconductor quantum dot-micropillar cavities. The aim is to identify a pillar containing a single quantum dot that can be used to develop an optical switch, an important component within a photonic network. We will investigate how to...

In this thesis we use optical spectroscopy to investigate III/V semiconductor quantum dot-micropillar cavities.
