Outline of Final Research Achievements |
Using a tellurite PCF, highly efficient dispersive wave was observed. The conversion efficiency from the pump light to the dispersive wave was as high as 65 %. This shows highly efficient wave length conversion from soliton to dispersive wave is possible. Supercontinuum generation in As2Se3 chalcogenide fiber was analyzed. It was shown that he normal dispersion range can be realized in the full transparent spectral range of this fiber and supercontinuum covering from 3 to 13 μm with high coherence can be generated in this fiber. In addition As2Se3 chalcogenide fiber was successfully was generated and supercontinuum extending to 10μm was generated for the first time.
