Research Abstract

In this grant we investigated "Resonantly-Guided optical Fibers". The fiber is a class of microstructured fibers consisting of sub-wavelength periodic array of high refractive index rods such as Si and chalcogenide glass embedded in silica cladding. By utilizing FDTD electromagnetic field simulations, we clarified various modal characteristics of the resonant fibers such as dispersion relation, mode notation, modal field profiles, and leakage losses. We also developed a novel FDTD algorithm to efficiently handle circular periodic structures.
