Integrated devices offer the ability to multiplex, miniaturize and engineer quantum light sources in ways that are inaccessible to more standard bulk systems. The goal of the work presented in this proposal is to exploit the benefits of integrated devices for continuous variable quantum optics. The first goal will be to create a miniature device that is capable of producing high levels of squeezing at the input wavelength of the device by combining second harmonic generation and optical parametric amplification into a single waveguide architecture. The second task will transfer ideas for the engineering of type II parametric downconversion sources from the discrete variable regime to continuous variable systems. Here we will explore how source engineering of the joint spectral amplitudes can be combined with the design of monolithic resonant devices in order to optimize nonlinear interaction for the efficient production of two-mode squeezing from an integrated device.
