Title: Ray based dynamical model applied to chalcogenide glass optical fibre
Abstract: The purpose of this project is to develop a ray dynamical model for the analysis of light in optical fibres. The ray dynamical model provides a probabilistic way to find the distribution of light intensity inside the fibre of any generic shape. The idea was developed from the application of ray dynamical analysis on 2D asymmetric resonant cavities (ARCs) or microcavities. The standard technique to illustrate the random behaviour of the light in irregular microcavities is in a Poincaré surface of sections (SOS) map and the SOS space can be divided into a finite number of pixels. Using Ulam’s method (Perron-Frobenius operator approach), a transfer matrix is generated using Markov chains and its spectrum is analysed. This enables the calculation of the net power delivered to the core.
