On the measurement of radiation induced crosstalk in polarization preserving optical fibers and directional coupler waveguides

The measurement of radiation induced crosstalk in optically coupled waveguide devices is presented. Experimental techniques used for the detection, processing and analysis of complex optical signal polarizations, intensities, and attenuations within an index-perturbed medium are shown to be formidable but manageable. Successfully measured and first reported crosstalk and absorption data occurring over eight decades of time are presented.<
