Abstract

In this work, we have analysed the feasibility of producing waveguides by direct fs-laser writing using astigmatic-elliptical beams generated with a SLM. As a consequence of the beam astigmatism two foci laying in orthogonal planes are produced, whose separation along the beam propagation axis and length-to-width aspect ratio can be controlled through the amount of astigmatic deformation of the wavefront.
