The waveguide is formed by a set of parallel tracks which constitute the depressed cladding. It is a key element for compact and efficient CW waveguide The results show that if the confinement factor, or mode size, is the criterion for comparison, there is little difference between the standard and depressed cladding cases for guides which are near the cutoff of the higher order modes. The primary difference is in the fraction of the mode which overlaps the cladding regions, 21 Dec 2017 Request (PDF) | Effect of cladding l | In this paper, the analytical study of the modal characteristics, cutoff condition and dispersion curves of circular optical waveguide having various cladding layers are presented. The proposed three structures of waveguide have three parts namely core with highest A method was developed for calculating the effective cutoff length, the size of a mode spot, and the chromatic dispersion over the profile of the refractive index (measured in the preform stage) of single-mode fiber waveguides with a depressed cladding. The results of such calculations are shown to agree with the results of use as lasers and routing waveguides. The results show that if the confinement factor, or mode size, is the criterion for comparison, there is little difference between the standard and depressed cladding cases for guides which are near the cutoff of the higher order modes. The primary difference is in the fraction of the mode The angles corresponds to waveguide modes in wave optics. • For thin Planar Waveguides x y z ns nc n1. Core. Substrate.
