Optical Assembly For 90° Polarization Rotation

摘要

Embodiments of an optical assembly for use in polarization rotation applications are disclosed. In one aspect, an optical assembly includes a polarization beam splitter a rotational element and a path exchange mirror. The temperature, wavelength and manufacturing dependencies of polarization rotation of this optical assembly are minimal to nonexistent compared to conventional Faraday rotation assemblies as the optical fiber accepts only the desired rotation. As such these optical assemblies have no temperature and wavelength dependencies of the polarization rotation angle over broad temperature and wavelength ranges with minimal additional losses.
