  • Abstract
    A compact nonreciprocal optical circuit for laser-diode-to single-mode-fibre coupling using a YIG sphere is proposed in the 1.3 ¿m wavelength region. It is clarified that the YIG sphere can function as an effective Faraday rotator as well as a coupling lens. A high isolation value of more than 30 dB has been realised with coupling efficiency of ¿5.2 dB for a single-mode fibre.
