New LiNbO3 devices for infrared interferometry and evanescent-field sensing: Integrated Single Mode Young's Slit Interferometer at 3.39µm
Résumé
We present an integrated Lithium Niobate device based on single mode behaviour of a planar waveguide at 3.39 μm, made by Titanium diffusion. After an experimental and theoretical study of the waveguide in the infrared, we present the set-up that allows an interferometric measurement of the emission spectrum and thus that can be applied as an integrated spectrometer. An integrated device such as presented here could be part of an astronomical instrument in order to study spectral characteristics of stars or exoplanets.
