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…
Investigation of the magnetic fluctuations in TbSnO ordered spin ice by high resolution energy-resolved neutron scattering
I. Mirebeau, H. Mutka, P. Bonville +2
We have studied magnetically frustrated TbSnO by neutron diffraction and high resolution energy-resolved neutron scattering. At 0.1 K, we observe short range magnetic c…
Ferromagnetic -spin glass transition induced by pressure in GdMoO
I. Mirebeau, A. Apetrei, I. Goncharenko +6
RMoO compounds show a ferromagnetic metal-insulator spin glass transition tuned by the radius of the rare earth ion R. We have studied GdMoO located…
Ferromagnetic - spin glass transition induced by pressure in the geometrically frustrated pyrochlore (TbLa)MoO
A. Apetrei, I. Mirebeau, I. Goncharenko +2
We have studied (TbLa)MoO pyrochlores by neutron diffraction and SR at ambient and under applied pressure. Substitution of Tb for La expands the lattice…
