摘要： Polarization independent optical isolator/circulator devices based on Mach-Zehnder interferometers. The devices utilize either polarization splitting and nonreciprocal polarization conversion or nonreciprocal phase shift within the interferometric arm. For devices with nonreciprocal phase shift, the relative phase difference is 0° in the forward propagation direction and 180° in the backward propagation direction, or vice versa, so that light goes into a bar or cross port depending on the propagation direction. The devices have advantages over previous designs in the use of inexpensive device components, simple alignment, minimal space requirement, and negligible polarization mode dispersion or polarization dependent loss. In addition, the devices can be made in a waveguide form with minimal loss and with high fabrication ease. An additional phase compensator and/or a variable attenuator can be integrated in order to relax the fabrication tolerances.

摘要： In a polarization-state converting apparatus for use as an optical isolator, an optical modulator and the like, there are provided a waveguide including a magnetic semiconductor, a device for applying a magnetic field to the waveguide in a first predetermined direction, a device for applying an electric field to the waveguide in a second predetermined direction, and a mode conversion is caused via electrooptic and magnetooptic effects due to the electric and magnetic fields to change the polarization state of light propagating through the waveguide. When used as an optical isolator, the optical isolation is performed to compensate for degradation of the mode conversion rate due to a phase mismatch between light incident upon the waveguide and light emerging from the waveguide. When used as an optical modulator, the optical modulation of light emerging from the waveguide is performed by varying the electric field and an optical isolation function is effected while compensating for degradation of the mode conversion rate due to a phase mismatch between light incident upon the waveguide and light emerging from the waveguide.
