ABSTRACT:
The present invention is directed to a circular-polarization maintaining fiber structure, containing a stress-applying filament whirling around a central core. The fiber is fabricable by any of the existing fiber-making methods. The fiber is capable of maintaining circular polarizations of light, segments of such fiber can be easily spliced by lining up the cores only, and the fiber tolerates well bending and random perturbations likely to occur in practice. The invention is immediately applicable to fiber gyroscope and other interferometric architectures, to a variety of sensors, and to coherent optical transmission.
