ABSTRACT:
The present invention provides for a reduced isolator assembly having only two elements for a linearly polarized light source. The first element may be a birefringent crystal or a linear polarizer, such as a linear polarizer sheet, a laminated thin-film polarizer, or a polarizing beam splitter. The second element is a quarter-wave plate. The isolator blocks the light reflected back toward the polarized light source.
