Abstract

In the proposed work such structures are to be numerically simulated in order to justify the expected behaviour, as well as measured experimentally. The samples for the experimental part of the study are being fabricated in Vilnius University. Related effects in axisymmetric structures, like self-collimation or axisymmetric focalization can be further investigated.

Description

Recently, interesting light beam propagation phenomena were discovered in so called axisymmetric photonic crystals in our research group in UPC together with collaborating group in Vilnius University. These phenomena are angular (spatial) filtering, also beam super-collimation. The axisymmetric structures, made by femtosecond pulse writing in nonorganic glasses in Vilnius University are very promising for microphotonic applications, as they have a huge potential for beam shaping and other manipulation. This could be a novel optical micro-component. several other beam propagation phenomena in axisymmetric structures, like flat lensing, self-collimations and others are to be explored, among others in our research group. Objective: Study of the axisymmetric diffusion in axisymmetric photonic crystals. The numerical – experimental investigation of the light propagation through such structures will be a topic of diploma work, and, if successfully finished, it will be result to a scientific publication in a journal of medium impact.
