Description

In this work we present experimental results for the generation of channel waveguides by a laser backwriting technique using a nanosecond pulsed Nd:YAG laser working at 1064 nm. We present a characterization of the resulting refractive index profile, using the refracted near-field technique, together with a spatially resolved chemical analysis based on energy dispersive x-ray analysis(EDX). The EDX results confirm that metal ions are embedded in a region close to the substrate interface, up to about a 5 μm depth. We also present a discussion of the physical mechanisms that produce the profiles measured
