摘要: We analyze frequency-shifting mechanisms in photonic crystal fibers (PCFs). In contrast to the generally used approach of launching pulses negative group velocity dispersion (GVD) region PCFs, we suggest employing a fiber with higher zero wavelength that is pumped positive GVD region. Results numerical optimization reveal amplitude stability frequency-shifted can be improved by more than 1 order magnitude and timing jitter arising from input fluctuations 2 orders proper choice dispersion. The presented will improve performance timing- amplitude-sensitive applications, such as nonlinear microscopy spectroscopy or optical synchronization for parametric chirped pulse amplification significantly.
