Analytic Expressions for Orbital Angular Momentum Modal Crosstalk in a Slightly Elliptical Fiber
Assuming weakly guiding approximation, we examine orbital angular momentum (OAM) mode mixing on account of ellipticity in a fiber and derive a complete set of analytic expressions for spatial crosstalk, using scalar perturbation theory that incorporates fully the existing degeneracy between a spatia...
