Abstract

In this work we analyze the effect of circular and azimuthal polarization in the inscription waveguides by fs-laser writing via ion migration effects in phosphate glass. The morphology of the produced structures indicates a reduction of non-linear refractive index for azimuthally polarized writing beams. Both radial and azimuthally polarized beams show transformation thresholds much higher than circularly polarized ones, along with a considerable increase of the size of the structures in the high energy regime.
