Abstract

Dependence of the optical properties of a microstructured (holey) fiber with a silica glass core on the refractive index of a liquid that fills the channels in the cladding has been studied. Optimum conditions ensuring a single-mode regime, high degree of the interaction of radiation with the liquid, and low losses are determined for the fiber with a silica glass core and a microcapillary structure geometry parameter of d/Λ = 0.9.
