    • The present multiple-stage optical isolator has low polarization-dependency and low polarization-mode dispersion but does not require a long time for the assembly. It is constructed of a first unit having a first Faraday rotator placed within a magnetic field and at least one birefringent crystal sandwiching the Faraday rotator, these components being arranged in order from the light incident side; and a second unit having a second Faraday rotator placed within a magnetic field and at least one birefringent crystal sandwiching the Faraday rotator, these components being arranged in order from the light incident side, wherein the first and second units are arranged in order along the direction of the light transmission.
    • 本发明的多级光隔离器具有低偏振相关性和低偏振模色散,但不需要较长的组装时间。 它由具有放置在磁场内的第一法拉第旋转器和夹着法拉第转子的至少一个双折射晶体的第一单元构成,这些部件从光入射侧依次布置; 以及第二单元,其具有放置在磁场内的第二法拉第旋转器和夹着所述法拉第旋转器的至少一个双折射晶体,这些部件从光入射侧依次布置,其中所述第一和第二单元沿着所述方向依次布置 的光传输。
