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…

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…
