ABSTRACT:
A multiple port reflection based circulator using a thermally expanded multiple core fiber. The circulator includes optical components to separate, rotate, and combine orthogonally polarized components of light in order to propagate light in one direction among consecutive cores of the fiber. The first and last cores of the fiber also being consecutive cores. The thermally expanded multiple core fiber enabling coupling to the circulator without the use of lenses.
