Abstract

Leaky surface acoustic wave velocity (V_LSAW) and attenuation profiles across the diameters of cladded glass fibers or fiber preforms are presented. Optical fibers with different dopants, such as GeO₂, F, B₂O₃, etc., and dopant concentrations have been investigated. The role of acoustic profiles across the core and cladding regions in the design of optical fibers for several device applications is outlined. By comparing V_LSAW profiles with the corresponding optical refractive index profile, n, the relation between ΔV _LSAW/V_LSAW and Δn/n is obtained for several dopants. Potential applications of cylindrical glass rods with graded acoustic-velocity profiles are also discussed
