Quantum information offers the promise of being able to perform certain communication and computation tasks that cannot be done with conventional information technology (IT). Optical Quantum Information Processing (QIP) holds particular appeal, since it offers the prospect of communicating and computing with the same type of qubit. Linear optical techniques have been shown to be scalable, but t...

In order to perform an experiment into optical phase-only correlation it was necessary to fabricate an SLM to the highest standards possible. Chapter five has provided a background to the electronic operation of the 16×16 SLM and the liquid crystal light modulation mechanism used in this project. Actual fabrication of a working spatial light modulator is an extremely delicate process requiring ...

All-optical spatial frequency filtering has a long history with many applications now commonly replaced digital alternatives. Although optical approaches are attractive in that they minimize energy requirements and images can be manipulated real time, relatively bulky compared to the compact electronic devices ubiquitous. With emerging interest nanophotonic all-optical information processing, t...
