Classical and Quantum Applications of Optical Four Wave Mixing in an Integrated Silicon Nitride Platform

Integrated photonics provide a very versatile platform for nonlinear optics experiments, due to the tight field confinement that high index contrast structures offer and their great degree of tunability. Two applications of optical four wave mixing, namely squeezed light generation and optical coherence control, are studied and original theoretical results are presented. A silicon nitride platform for integrated nonlinear optics is then developed and devices are designed to demonstrate two mode squeezing generation, as well as optical data frequency conversion and a metrology application.
