    The circulator is an irreversible one-way three-port component to allow light propagate in a specific direction. Circulators can be divided into non-polarization-maintaining circulator and polarization-maintaining circulator.
    The non-polarization-maintaining circulator consists of birefringent beam displacer, polarization element, Faraday rotator, half-wave plate and collimator. 
    The polarization-maintaining optical circulator consists of input polarizer, Faraday rotator, half-wave plate, output polarizer and collimator. 
    CASTECH produces circulators with low insertion loss, high isolation, low polarization dependent loss and excellent temperature stability, with the center wavelength of 450~2000nm. The connection of the fiber tail can be bare fiber, FC/PC or FC/APC.
