LIGHT POLARIZATION MODULATION IN SINGLE-MODE OPTICAL FIBERS

A theoretical and experimental study of light polarization modulation in single-mode anisotropic optical fibres is presented. The problem of increasing polarization modulation efficiency in slightly and strongl y anisotropic fibres is considered. The requirements to be met by the optical configuration for efficient polarization modulation with both slightly and strongly anisotropic fibres are discussed. The polarizati on modulation signal is found to be immune to external effects on the fibre under compensated birefringence. An experimental polarization mo dulation-based 'fibredyne' video transmission data highway is presente d.
