Transmission of orthogonal circular polarizations on a fiber

摘要: A beam source for a heterodyne interferometer generates containing components with different frequencies and respective orthogonal circular polarizations directs the down an isotropic single-mode or few-mode optical fiber. Polarizations of light exiting fiber are converted to linear use in interferometer, where frequency separated according polarization. Crosstalk between left-handed right-handed is low, which permits clean separation components. quarter-wave plate other element that converts polarization has mounting tilt roll angle adjustments adjust exit depend on bends The can have rigid jacket fast relaxation time provide stable output.
