Photonic crystal fibres may be divided into classes of which the two major ones are the index-guiding or high-index core fibres and the photonic bandgap or low-index core fibres. In this chapter, we will describe the fundamental properties of high-index core fibres, in which the waveguiding principle may be expressed as modified total internal reflection (MTIR). In high-index core PCFs, the core will — as expressed by the name - have a higher effective refractive index value than the surrounding cladding material. However, these effective refractive indices are typically obtained through the introduction of air holes, which may be ordered in different patterns, and which may have different dimensions, shapes etc.
