Nano Fiber with a Metal Clad
Abstract:In this article we theoretically analyzed the beam propagation properties of an optical nano fiber with a metal clad. By solving the Maxwell's equations for this fiber and applying suitable boundary conditions the behavior of the propagation constant as a function of the core radius or clad radius is investigated. Our study shows that electromagnetic fields are localized at the two metal–dielectric interfaces with a beam diameter less than the wavelength and the field decay evanescently on both sides of each interface. The linear dependency of the propagation constant on the refractive index of the surrounding medium shows that the silicon nano fiber with a silver clad is promising for the development of miniaturized optical sensors with high sensitivities.
