Adaptive resolution of fine scales in modes of microstructured optical fibers
Jay Gopalakrishnan, Jacob Grosek, Gabriel Pinochet-Soto +1
An adaptive algorithm for computing eigenmodes and propagation constants of optical fibers is proposed. The algorithm is built using a dual-weighted residual error estimator. The r…
Sensitivity of Confinement Losses in Optical Fibers to Modeling Approach
Pieter Vandenberge, Jay Gopalakrishnan, Jacob Grosek
A prime objective of modeling optical fibers is capturing mode confinement losses correctly. This paper demonstrates that specific modeling choices, especially regarding the outer…
Computing leaky modes of optical fibers using a FEAST algorithm for polynomial eigenproblems
Jay Gopalakrishnan, Benjamin Quanah Parker, Pieter Vandenberge
An efficient contour integral technique to approximate a cluster of nonlinear eigenvalues of a polynomial eigenproblem, circumventing certain large inversions from a linearization,…
