Abstract

Liquid-core optical fibers (LCOFs) have recently been identified as extremely attractive waveguides for applications to frequency conversion and supercontinuum (SC) generation [1-4]. Their advantages over silica optical fibers include broad visible to mid-infrared transparency and enhanced material nonlinearities by physical processes specific to anisotropic liquid molecules [3]. As a result, there has been extensive interest in the use of nonlinear liquids, such as CS₂ or ethanol, for applications in visible and mid-infrared SC generation [2-4].
