Abstract
The peak intensity of an ultrafast laser pulse focused inside a dielectric material can be sufficiently high to drive the nonlinear absorption of the laser light. This deposition of energy in the focal region can result in a localised material modification. This modification can in turn manifest itself through changes to the chemical etch rate and / or refractive index. Using these manifestations, it is possible to manufacture three-dimensional photonic components, such as optical waveguides. In this talk, I will discuss how ultrafast laser inscription can be used to manufacture three-dimensional photonic components for the manipulation of spatial modes.
