Abstract

The refractive index profile, or cross-section, of an optical waveguide is its most defining property. It directly determines the number of transverse modes supported by the waveguide and the properties of these modes. Proper control of the waveguide cross-section is therefore essential if the performance of the waveguide, or waveguide device, is to be optimised. This chapter describes how the waveguide cross-section affects the properties of the guided modes, why it is important to control the waveguide cross-section from a device engineering point of view and the various experimental techniques that have been developed to control the cross-section of ultrafast laser inscribed waveguides.
