Paper Abstract

We have developed novel bismuth-based photonic crystal fiber which exhibits high nonlinearity γ ~ 780W-1km-1 and relatively low group-velocity-dispersion D ~ -25 ps/nm/km at 1560 nm. The new fabrication process was also developed for this novel photonic crystal fiber with 6-fold symmetric structure. The core diameter 2.7 μm of this fiber was designed to have modelately decreased normal dispersion and high nonlinearity. Spectral broadening induced by self-phase-modulation by 1550 nm fs-pulse propagation shows that the high nonlinearity and dispersion reduction is simultaneously achieved.
