Explanation of polarisation dependence of differential phase shift in two-mode elliptic-core fibre strain gauges
An appropriate elliptic-core fibre theory is applied to model the differential phase shift between the first- and second-order modes observed in recent experiments on two-mode elliptic-core fibres subjected to longitudinal ...
Design of a mode filter consisting of two dual-mode highly elliptical-core fibers
Coupling characteristics of directional couplers consisting of two dual-mode highly elliptical-core fibers have been studied in detail using a first-order perturbation approach, and two different designs of a mode filter ...
A simple and accurate model analysis of strip-loaded optical waveguides with various index profiles
A simple first-order perturbation approach has been developed to study the propagation characteristics of strip-loaded diffused waveguides with various refractive index profiles. Propagation constants of the guided modes ...
