Modal dispersion curves of an optical waveguide with a core cross-section partially bounded by one turn of an equiangular spiral under weak guidance approximation

Analysis Of Waveguide Whose Guiding Region Filled With Dielectric Material Bounded By Two Equiangular Spirals Separating It From Two Dielectric Cladding Regions

“…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.…”
