ABSTRACT:
A method of providing a beam having precisely orthogonally polarized components includes generating a beam with substantially orthogonally polarized components, splitting the beam to separate the components to separate paths, projecting each component into a respective polarization preserving optical fiber (PPF) or polarizing fiber, recombining the components output from the fibers into a single beam, and transmitting the single beam to an interferometer. The PPFs are rotationally adjustable at their output ends to provide precise orthogonality in the resulting beam.
