Surface-polariton fiber polarizers with high polarization extinction ratio

We polished 633-nm single-mode fibers embedded in curved silicon V-shaped grooves. Polished samples of high quality were ensured in liquid-drop measurements and were inspected by using an atomic force microscope. Fibers so polished existed a long effective length and negligible loss. We subsequently sputtered MgF/sub 2/ and aluminum films on polished fiber surfaces and demonstrated fiber polarizers with high polarization extinction ratio. Our devices satisfied the Malus' law well. To our best knowledge, this was the first time such kinds of surface polariton fiber polarizers having a long effective interaction length were demonstrated.
