In this report, we present the design of a holey fiber structure with six air holes in the cladding and a transverse microfluidic channel intersecting the silica core for the purpose of liquid detection. The simulation results suggest an improved refractive index sensitivity of the proposed structure compared to that of a single mode fiber with a similar transverse channel. The proposed holey fiber structures are fabricated and characterized.
