All-fiber polarizer with a null coupler

Abstract

We report a new fiber polarizer based on a null coupler. It is a fused taper coupler made from two markedly dissimilar fibers.1 Each input fiber carries two modes in its core (the two polarizations of the "single" mode), making four modes in all. Along the coupler, each evolves adiabatically into just one mode of the cladding waveguide at the narrow circular coupler waist. The four corresponding modes of the waist are the HE11x HE11y TE01, and HE21c hybrid modes2 (see Fig. 1). This evolution is reversed at the output taper.
