Waveguide Resonator with Integrated Phase Modulator for Second Harmonic Generation
Michael Stefszky, Matteo Santandrea, Felix vom Bruch +6
We report second harmonic generation from a titanium indiffused lithium niobate waveguide resonator device whose cavity length is locked to the fundamental pump laser using an on-c…
General analytic theory of classical collinear three wave mixing in a monolithic cavity
Matteo Santandrea, Michael Stefszky, Christine Silberhorn
Integrated, monolithic nonlinear cavities are of high interest in both classical and quantum optics experiments for their high efficiency and stability. However, a general, analyti…
Cryogenic second harmonic generation in periodically-poled lithium niobate waveguides
Moritz Bartnick, Matteo Santandrea, Jan Philipp Hoepker +7
Prospective integrated quantum optical technologies will combine nonlinear optics and components requiring cryogenic operating temperatures. Despite the prevalence of integrated pl…
An interferometric method for determining the losses of spatially multi-mode nonlinear waveguides based on second harmonic generation
Matteo Santandrea, Michael Stefszky, Ganaël Roeland +1
The characterisation of loss in optical waveguides is essential in understanding the performance of these devices and their limitations. Whilst interferometric-based methods genera…
Characterisation of Inhomogeneities in Ti:LiNbO waveguides
Matteo Santandrea, Michael Stefszky, Ganaël Roeland +1
Nonlinear processes in integrated, guiding systems are fundamental for both classical and quantum experiments. Integrated components allow for compact, modular and stable light-pro…
General framework for the analysis of imperfections in nonlinear systems
Matteo Santandrea, Michael Stefszky, Christine Silberhorn
In this paper, we derive a framework to understand the effect of imperfections on the phasematching spectrum of a wide class of nonlinear systems. We show that this framework is ap…
