Supermode-based second harmonic generation in a nonlinear interferometer
David Barral, Virginia D'Auria, Florent Doutre +7
We demonstrate supermode-based second harmonic generation in an integrated nonlinear interferometer made of linear and nonlinear directional couplers. We use a fully-fibered pump s…
Configurable heralded two-photon Fock-states on a chip
Xin Hua, Tommaso Lunghi, Florent Doutre +10
Progress in integrated photonics enables combining several elementary functions on single substrates for realizing advanced functionnalized chips. We report a monolithic integrated…
Photorefractive effect in LiNbO-based integrated-optical circuits for continuous variable experiments
François Mondain, Floriane Brunel, Xin Hua +7
We investigate the impact of photorefractive effect on lithium niobate integrated quantum photonic circuits dedicated to continuous variable on-chip experiments. The circuit main b…
Lithium niobate waveguides with high-index contrast and preserved nonlinearity fabricated by High Vacuum Vapor-phase Proton Exchange
Alicia Petronela Rambu, Alin Marian Apetrei, Florent Doutre +4
Highly confining waveguides without degraded nonlinear coefficient and low propagation losses have been fabricated in lithium niobate by a new process that we called High Vacuum Va…
Chip-based squeezing at a telecom wavelength
François Mondain, Tommaso Lunghi, Alessandro Zavatta +5
We demonstrate a squeezing experiment exploiting the association of integrated optics and telecom technology as key features for compact, stable, and practical continuous variable…
Broadband integrated beam splitter using spatial adiabatic passage
Tommaso Lunghi, Florent Doutre, Alicia Petonela Rambu +7
Light routing and manipulation are important aspects of integrated optics. They essentially rely on beam splitters which are at the heart of interferometric setups and active routi…
Soft-proton exchange on Magnesium-oxide-doped substrates a route toward efficient and power-resistant nonlinear converters
T. Lunghi, F. Doutre, G. Legoff +5
Despite its attractive features, Congruent-melted Lithium Niobate (CLN) suffers from Photo-Refractive Damage (PRD). This light-induced refractive-index change hampers the use of CL…
Quantum photonics at telecom wavelengths based on lithium niobate waveguides
Olivier Alibart, Virginia D'Auria, Marc De Micheli +6
Integrated optical components on lithium niobate play a major role in standard high-speed communication systems. Over the last two decades, after the birth and positioning of quant…
