“…Among the non-circular cross-sections there are the triangular, elliptical, planar, polygonal and other more complicated shapes investigated [1][2][3][4][5][6][7][8][9]. Dielectric plane slab waveguides form the basic building blocks of a variety of devices in the field of integrated optics, laser beam technology, and microwave communications.…”

“…Since the transmission properties of optical waveguides essentially depend on the cross-sectional geometry and the nature of the material used to fabricate the guide, considerable amount of investigations have been dedicated towards the wave propagation through guides of varieties of cross-sections [1][2][3][4][5][6][7][8][9][10][11][12][13] as well as composites [14][15][16][17][18][19][20]. Most of the explored optical waveguides are now widely recognized, and implemented in various issues related to optics and photonics.…”

Abstract-An analytical investigation of the lightwave propagation through dielectric optical fibers with helical clads is presented with the emphasis on their hybrid field patterns. The helical clad section is effectively realized by introducing conducting windings on the core-clad boundary. Using Maxwell's equations, a rigorous analytical approach is implemented to determine the higher order field patterns in such fibers. For simplicity, two particular values of the helix pitch angle are considered, viz. 0 • and 90 • . The nature of fields is presented in both the situations corresponding to different allowed values of the propagation constants and the fiber diameters. The radial distributions of fields corresponding to hybrid modes are presented under different situations, which exhibit the patterns like spikes. The observed smooth match of the fields at the core-clad interface validates of our analytical approach. The presence of a little higher amount of field in the fiber clad section is essentially attributed to the helical windings introduced over the fiber core. Further, the existence of considerable amount of evanescent waves in such fibers opens up the possibility of their applications in optical sensing.

“…Optical waveguides have been investigated extensively during the past four decades, and such guides with various forms of geometrical crosssections have been explored in the literature [1][2][3][4][5][6][7][8][9]. Fibers with helical structures fall under the category of complex waveguides, and these have drawn considerable interest among the R&D community owing to the much use of helical structures in all low and medium power traveling wave tubes (TWTs) [10].…”

Abstract-The paper presents the electromagnetic (EM) wave propagation in cylindrical optical fibers with helical windings under slow-and fast-wave considerations. Field components are deduced for both the cases, and also, the dispersion relations are obtained by applying the boundary conditions, as modified by the presence of conducting helical windings. Two special cases are considered corresponding to the values of the helical pitch angle as 0 • and 90 • . A comparison of the dispersion relations is presented.
