Outline of Final Research Achievements

To be developed for optofluideics applications were two types of liquid-core/liquid-cladding optical waveguides (LLW), i.e., 1) LLW based on the wall effect of glass capillary tubing using laminar flow of mixture of water and organic solvent, 2) dynamic LLW based on the tube radial gradient of the linear flow velocity in segmented laminar flow in capillary tubing. However, strong guided light was not observed in both cases. Instead, characterization of LLW based on tube radial distribution of ternary mixed solvents was thoroughly done.
