1. A layered sheet isolator comprising:
a first planar layered sheet polarizer comprising a multilayered structure including multiple planar, transparent, non-dichroic, low-absorption layers including first non-dichroic layers having a relatively high index of refraction and second non-dichroic layers having a relatively low index of refraction, the first and second layers being arranged in an alternating manner within the structure so as to form resonator structures, and a planar dichroic layer positioned within the multilayered structure;
a second planar layered sheet polarizer also comprising a multilayered structure including multiple planar, transparent, non-dichroic, low-absorption layers including first non-dichroic layers having a relatively high index of refraction and second non-dichroic layers having a relatively low index of refraction, the first and second layers being arranged in an alternating manner within the structure so as to form resonator structures, and a planar dichroic layer positioned within the multilayered structure, the second planar layered sheet polarizer having a 45° misalignment relative to the first planar layered sheet polarizer; and
a Faraday rotator positioned between the first and second planar layered sheet polarizers.
