Abstract
The purpose of this chapter is to collect experimental details and background material that are common to multiple chapters of this thesis. Section 2.2 discusses a model of spontaneous parametric down conversion and details various experimental down conversion setups used for multi-photon state generation: each description will refer to the chapters where they are employed. Section 2.3 reviews the underlying concepts of waveguide optics required for this thesis. Finally, Sect. 2.4 describes three different waveguide architectures that are employed in the experiments reported in this thesis. Simulation and fabrication of these architectures lies outside the scope of this thesis, and were performed by colleagues as stated in each corresponding section.

Notes
- 1.
Where we define collection efficiency of one mode \(A\) of two modes \(A\) and \(B\), as the total number coincidences detected from modes \(A\) and \(B\), divided by the total number of single photon events detected from mode \(A\); note that this definition involves the detector efficiency.

The closest standard fibre-array seperation is \(127\,\upmu \)m.
