Our latest work in softphotonics features the seamless integration of liquid-core fibers into standard fiber systems, achieving unprecedented advancements in nonlinear optics and signal processing. Utilizing liquids like CS2 and halocarbonates, we have developed a reliable splicing technique with standard fibers, enabling low-loss all-fiber interconnectivity. This breakthrough provides insights into intra-fiber thermodynamics and enables robust, long-term applications in optical signal processing in the near-infrared. Our method opens new avenues for exploring negative pressures and facilitating multi-laser excitation for cross-phase modulation, showcasing the potential of liquid-filled fibers in future optical technologies.
