Abstract :
A finite-element approach with the aid of the perturbation technique is used to determine the complex propagation characteristics of lossy metal-clad optical fibres. The fundamental optical modal field profiles of these structures for the pure TE and TM polarisation are investigated. Metal-clad optical fibres of submicron dimensions find an important application in near-field optical scanning microscopy, a technique rapidly developing in recent years, providing high-resolution imaging in the semiconductor industry and in applications in the biological sciences
