  • Abstract
    A compact Faraday-rotation 4-port circulator was developed for the near-infrared region. This circulator consists of an yttrium-iron-garnet Faraday rotator, biased by two permanent magnets, and two Glan-Taylor prisms. Insertion losses of 2.7¿3.2 dB and isolation ratios of 13¿28 dB among non-reciprocal ports were obtained at 1.15¿m wavelength.
