Paper Abstract

Monte Carlo approach is applied to simulate light transmission and emission characteristics of a dielectric multimode waveguide of a semi-toroid shape, for range of geometrical and optical parameters of the system. The physical description of light transport is based on classical Fresnel formulas used to define probability of single photon transmission/reflection at the core/cladding boundary. Even positional and angular distribution of 'emitters' launching photons into the waveguide within cones defined by critical angle was employed to simulate propagation of all meridian and skew rays. No interference effects are included in the model. The calculated results allow for direct assessment of light leaks from and transport through the waveguide core in dependence on system parameters.
