MICROBENDING LOSSES OF BOW-TIE AND SIMILAR ANISOTROPIC FIBERS

Microbending behavior of bow-tie fibers is investigated theoretically. Our results for the practically existing case of unequal core and cladding anisotropy agree satisfactorily, in a statistical sense, with published experimental data. In the ideal case of equal core and cladding anisotropy, our results confirm the prediction by Snyder and Ruehl that the polarizing behavior of a long bow-tie fiber with microbends is caused by the 'small field' effect.
