Abstract
Apparatus for depolarizing light in fiber optics, comprises of a pair of fiber optic collimators and plurality of contiguous slabs of linear birefringent plates arranged in a stack forming a parallel slab. The optical axes of said linear birefringent plates are approximately 45 degrees with respect to each other. Thicknesses of said linear birefringent plates are such that their individual polarization mode delays exceed coherence time of a beam defined by an optical source.
