A New Compact Expression for the Powers of Hybrid Modes of the Step-Index Optical Fiber
arXiv:2005.01363
Abstract
A new, compact, and exact general expression is developed for the powers of hybrid EH- and HE-modes of the standard step-index optical fiber. The expression is found with the help of the Pauli matrices. The expression is reducible to widely used approximate forms for hybrid mode powers of weakly-guided fibers.
