Optical isolators for long-wavelength fiber-optic communication systems

Abstract

High-bit rate long-wavelength optical fiber communication systems are likely to require broadband optical isolators capable of operating over the wavelength range containing both of the silica fiber loss minima, i.e., 1.3 and 1.55 μm. Present optical isolators are generally based on the magnetooptic Faraday effect and incorporate a suitable magnetooptic crystal, usually yttrium iron garnet Y3Fe5O12, to rotate nonreciprocally by 45° the plane of polarization of the transmitted and reflected radiation.1-3 Since the Faraday rotation is strongly wavelength dependent, these devices are narrow band and only produce useful optical isolation near the design wavelength.1
