A comparative study of the modal dispersion curves of fibers with different degrees of metal loading on the core-cladding interfaces

Abstract

We obtain the characteristic equations and modal dispersion curves of optical fibers with different degrees of metal loading on the core–cladding boundary. If p is the fraction of the circular boundary which is metal loaded, we consider four cases, so that p takes the values 1/4, 1/2, 2/3, and 3/4 successively. A comparison of the dispersion curves shows that, as p increases, the number of modes sustained also increases, the other parameters like the operating wavelength (λ), the core and cladding refractive indexes (n1 and n2), and the core radius (a) being kept constant. © 2000 John Wiley & Sons, Inc.

Modal Dispersion Characteristics of a Single Mode Dielectric Optical Waveguide With a Guiding Region Cross-Section Bounded by Two Involuted Spirals

“…New material like metallic, chiral materials, liquid crystals, magnetic crystals etc have also been introduced as constitutive materials for new kinds of unconventional waveguides in either core or cladding [14][15][16][17][18][19][20][21][22][23][24][25][26]. These smart structured waveguides with smart materials provide a rich variety of characteristics; several books and research papers have appeared in this area.…”
