Index contrast tunability of LiNbO waveguides obtained by thermal treatment
Mihnea Raoul Sandu, Alicia Petronela Rambu, Laura Hrostea +1
The actual techniques allowing the fabrication of waveguides in lithium niobate are not able to satisfy one of the demands of modern integrated photonics namely well-controlled tun…
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…
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…
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…
Anomalous dispersion in Lithium Niobate one-dimensional waveguide array in the near-infrared wavelength range
Alin Marian Apetrei, Alicia Petronela Rambu, Christophe Minot +3
Knowing the dispersion regime (normal vs anomalous) is important for both an isolated waveguide and a waveguide array. We investigate by the Finite Element Method the dispersion pr…
