Integrated liquid-core optical fibers (LCOF) have recently emerged as new photonic platforms for their wide range of potential applications in nonlinear photonics [1,2]. Their advantages over solid-core glass fibers include broad transparency from the UV to the mid-IR and enhanced nonlinear optical effects. For instance, enhanced stimulated Raman scattering (SRS) has recently been demonstrated using carbon disulfide, Toluene or ethanol nonlinear liquids in integrated all-fiber systems compatible with standard single-mode fibers (SMFs) [1,2].
