A Multi-D-Shaped Optical Fiber for Refractive Index Sensing

Sensors, 2010
A novel class of multi-D-shaped optical fiber suited for refractive index measurements is presented. The multi-D-shaped optical fiber was constructed by forming several D-sections in a multimode optical fiber at localized regions with femtosecond laser ...

Supermode Characteristics of Nested Multiple Hollow-Core Anti-Resonant Fibers

Photonics, 2022
Mode-division multiplexing (MDM) can achieve ultra-high data capacity in optical fiber communication. Several impressive works on multicore fiber (MCF), multi-mode fiber, and few-mode multicore fiber have made significant achievements in MDM.

Systematic approach for designing zero-DGD coupled multi-core optical fibers

Optics Letters, 2016
An analytical method is presented for designing N-coupled multi-core fibers with zero differential group delay. This approach effectively reduces the problem to a system of N-1 algebraic equations involving the associated coupling coefficients and propagation constants as obtained from coupled mode theory.

Fast and accurate modelling of nonlinear pulse propagation in graded-index multimode fibers [PDF]

, 2017
We develop a model for the description of nonlinear pulse propagation in multimode optical fibers with a parabolic refractive index profile. It consists in a 1+1D generalized nonlinear Schr\"odinger equation with a periodic nonlinear coefficient, which ...

Optical coupling for multi-layer printed wiring board by selfwritten waveguide [PDF]

, 2015
For the future of optical interconnect, high optical coupling efficiency is required for high density multilayer optical printed wiring board (OPWB). Hence, we propose optical pin as optical coupling devices between surface devices and the multi-layer ...
