Abstract
Planar waveguides have been prepared on the ZrO2-(3-glycidiloxypropyl)trimethoxysilane (GPTS) system. Stable sols containing ZrO2 nanoparticles have been prepared and characterized by Photon Correlation Spectroscopy. The nanosized sol was embedded in (3-glycidoxipropil)trimethoxisilane (GPTS) used as a hybrid host for posterior deposition. The optical parameters of the waveguides such as refractive index, thickness and propagating modes and attenuation coefficient were measured at 632.8, 543.5 and 1550 nm by the prism coupling technique as a function of the ZrO2 content. The planar waveguides present thickness of a few micra and support well confined propagating modes. Er3+ doped samples display weak and broad (Δλ≈96nm) emission at 1.5μm.
