Outline of Final Research Achievements

It was shown that tellurite and fluoride glass can generate supercontinuum reaching their infrared absorption edges. In case of fluoride, it can generate supercontinuum covering the spectral range over 5 octaves from its ultra violet absorption edge to infrared absorption edge. We successfully fabricated the hybrid photonic crystal fibers which can control the chromatic dispersion with high freedom using core and cladding with different glass systems. We showed that supercontinuum extending to the mid-infrared region can be generated and broadband parametric amplification gain can be realized using the hybrid photonic crystal fibers with flattened chromatic dispersion spectra. It was shown from this research project that coherent light generation and processing which cannot be realized by silica fibers can be achieved using the hybrid photonic crystal fibers made of non-silica highly nonlinear glasses.
