Abstract

A single-mode fiber Faraday rotator is proposed and fabricated by using a paramagnetic glass with a high Verdet constant. The Faraday rotator is a W-fiber with three layers, namely, core, inner cladding, and outer cladding. To make the fiber FR-5 is used as the starting material. The Verdet constant of the rotator is −0.25 min/Oe·cm at a 0.633-μm wavelength. The rotator can be used in a fiber isolator.
