Abstract
A unique solid core lead silicate photonic crystal fiber has been designed which promises to simultaneously exhibit large optical nonlinearity and almost uniform low dispersion. At 1064 and 1550Â nm wavelengths, the fiber is expected to exhibit nonlinear coefficient ~ 1420 W-1 km-1 and ~ 923 W-1 km-1, respectively, and dispersion ~ 7Â ps/km/nm and ~ 40Â ps/km/nm, respectively. Employing numerical simulation, we have investigated supercontinuum (SC) generation in this fiber by pumping 1Â ps and 50Â fs pulses. An octave-spanning SC from 680 to 1500Â nm is achievable at the end of 15Â cm long fiber by pumping 50Â fs pulses of 50Â W peak power at 1064Â nm. SC spectra from 1200 to 2600Â nm are also achievable by pumping 50Â fs pulses of 100Â W peak power at 1550Â nm. The simulated SC spectra due to 50Â fs pulses are attributed to self-phase modulation. A flat spectrum from 650 to 980Â nm is predicted due to pumping in the normal dispersion regime at 800Â nm using 1Â ps pulses of 300Â W peak power in a 75Â cm long fiber.
