| Outline of Final Research Achievements |
・It was shown shown that As2Se3(core)/AsSe2(first cladding)/As2S5(seconf cladding) chalcogenide double clad fiber had the normal dispersion in the mid- infrared region. Uisng this double clad fiber, mid-infrared highly coherent supercontinuum covering 2-14 μm was obtained for the first time. It was shown that chalcogenide double clad fiber is a promising medium for mid-infrared highly coherent supercontinuum generation.
・All-optical dynamic photonic band gap control by optical Kerr effect was demonstrated in an all-solid double-clad tellurite photonic band gap fiber which was fabricated using TeO2-Li2O-WO3-MoO3-Nb2O5 glass,TeO2-ZnO-Na2O-La2O3 glass and TeO2-ZnO-Li2O-K2O-Al2O3-P2O5 glass. The transmission spectrum was simulated with the pump peak power increasing from 0 to 300 kW. At the pump peak power of 200 kW and the signal of 1570 nm, dynamic PBG control with 10 ps speed was achieved in this tellurite photonic band gap fiber theoretically and experimentally for the first time.
