Abstract
A chiral optical fiber polarizer is provided that is capable of being fabricated in-line along a conventional polarization maintaining fiber having external structural element(s), positioned between two optical fiber portions, and includes a modified central portion with altered fiber cladding interface elements on each side thereof. The modified central portion includes at least one diameter reduced sub-section that allows a light signal to propagate simultaneously in the core and in at least one external structure element, and at least one diameter expanded sub-section that allows the light signal to propagate substantially in the core, where the modified central portion is configured to be operable to serve as a polarizer for light signals with linear polarization components.
