Abstract
Spectral and coherence evolutions were measured for supercontinuum (SC) generated in a 2.7 cm highly nonlinear tellurite photonic crystal fiber. Numerical simulations were performed based on the generalized nonlinear Schrödinger equation with noise. The measurements show that coherence degradation first occurs after soliton fission, and then spreads to longer wavelengths as the average power of the SC increases. The solitonic coherence shows much slower degradation than the overall coherence.
