Magneto-optical nanoparticle-doped silica-titania planar waveguides

Résumé

This letter describes how composite material, made of maghemite ‐ nanoparticles embedded in a silica∕titania matrix, can be used to develop new magneto-optical planar waveguides. Thin film samples are coated on Pyrex™ substrates from a magnetic particles doped sol-gel preparation. -lines spectroscopy measurements performed on these samples show that an out of plane magnetic field applied during the gelation induces a decrease of the planar waveguide phase mismatch. Free space measurements evidence the Faraday rotation of the films up to at 633 nm. Improvements and leads of further works are proposed in term of magneto-optical waveguide applications.
