  • Abstract
    Compact Faraday rotation isolators have been developed for near-infrared radiation. Two types of Faraday rotators were used: one was composed of two permanent magnets, the other of a closed magnetic circuit with a permanent magnet. 2.0 dB insertion loss and 30 dB isolation ratio at 1.15 ¿m wavelength have been obtained.
