Abstract
A polarization-independent optical isolator comprises three Faraday rotators and four birefringent elements. An optical arrangement of these elements is determined on the basis of the appropriate values derived from the analysis for polarization-independency. A transmission loss characteristic, which is most important in practical use of the optical isolator, is maintained at an excellent level even in presence of variation in temperature and wavelength and in presence of fluctuation in working precision. Deterioration of various isolator properties can be avoided.
