“…Unconventional waveguides with core cross-sections such as elliptical, rectangular, triangular, pentagonal, annular, spiral, cardioids etc. have been studied by the several researchers [1][2][3][4][5][6][7][8][9][10][11][12][13]. Such unconventional waveguides play an important role in the design and operation of many integrated optical devices such as wavelength filtering, coupling and semiconductor laser technology.…”

Abstract-With the use of scalar field approximation we make an analytical study of a dielectric waveguide whose core cross-section is bounded by two spirals of the form 1 r = ξθ. This waveguide is similar to that of a distorted slab waveguide in which both a curvature and a flare are present. We derived the modal characteristic equation by analytical analysis under the weak guidance approximation. We find the modal dispersion curve, which support only single mode propagation and the same compared with the same kind of waveguide with metal claddings.

Abstract-The single mode condition of rectangular waveguides is derived by using a simple ray-optics approach, which relies on geometrical ray tracing principles as in classical optics.Light propagation through such a waveguide can be approximately simplified as reflections within two planes of incidence. By employing the mode equations for different polarizations, a relation that shows the singlemode cut-off as a function of the waveguide dimensions is readily obtained.

“…Most of these guides are now widely recognized for their use in the fabrication of IO circuits and laser beam technology. A few examples of such guides are tapered and elliptical fibers [1][2][3][4][5], rectangular and planar [6][7][8][9][10], triangular [11][12][13][14], parabolic cylindrical [15][16][17][18], polygonal [19] and Piet Hein [20,21] type guides, the study of which have been presented using numerical and partially analytical techniques.…”

Abstract-A study is presented of the light wave propagation in a new type of dielectric optical waveguide with hyperbolic kind of crosssection. Further, the waveguide is assumed to have a conducting helical winding. The analysis essentially requires the use of elliptical coordinate system, which finally results into Mathieu and modified Mathieu functions as the representatives of the electromagnetic fields within the lightguide. Field components in the different sections of the guide are deduced, and the characteristic dispersion equation for the system is derived. The preliminary investigation on such type of waveguide throws the idea that the presence of helix pitch angle (which serves the purpose of additional controlling parameter for the guide) in the dispersion relation would greatly affect the propagation characteristics of the guide, and this can be of great practical importance.
