The promise of optical squeezing for enhanced metrology has been emphatically demonstrated in recent integration experiments in gravitational-wave detectors such as GEO600 and LIGO . Furthermore, squeezed light is the fundamental building block for continuous variable optical quantum computing and provides tests of fundamental physics, such as entanglement. As was seen for fibre optical networks, it is expected that ubiquitous usage of squeezed states will require a platform for their generation and manipulation that is miniaturized, stable, reproducible, and fibre compatible.

In this talk I will present recent work towards producing strongly squeezed states of light in an integrated architecture – titanium indiffused lithium niobate waveguides. I will begin by introducing squeezed states and how they are typically produced via the second-order nonlinearity . From there an overview of waveguide systems and a short introduction to waveguide production methods will be shown. Finally, recent results from experimental second harmonic generation and squeezed light generation from waveguide resonators will be presented.
