Abstract

Using Maxwell's equations subject to suitable boundary conditions, a preliminary investigation of the propagation characteristics of a tapered optical fiber with helical windings is performed. Eigenvalue relations are developed followed by the discussion on the cutoff situations. Plots of the dispersion relations are presented corresponding to two particular values of the helical pitch angle, namely 0° and 90°, and the results are compared. It is observed from the dispersion relations that the helix pitch angle would greatly affect the modal characteristics of the guide, making thereby the angle of pitch as one of the dominant controlling parameters, so far as the fiber design is considered. This is further verified through the comparison of results with those obtained for dielectric tapered fibers without helical windings.
