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 ...
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 ...
Oscillating two-stream instability of a lower hybrid wave in an inhomogenous plasma
The effect of the density inhomogeneity on the oscillating two-stream instability of a lower hybrid pump wave with a finite wavelength is investigated. The density inhomogeneity introduces dephasing that restricts the ...
Scalar modes and coupling characteristics of eight-port waveguide couplers
The scalar modes and the coupling characteristics of an eight-port waveguide coupler consisting of four parallel single-mode waveguides are discussed. The analysis is based on a rectangular waveguide model which has been ...
