ABSTRACT
Cross-phase modulation (XPM) in a silicon wire waveguide at 1.55 μm telecom band was studied down to ultralow light levels. In the low-power regime, we found that free-carrier dispersion as well as the optical Kerr effect contributes to the XPM. Possible mechanisms of the low-power XPM are discussed.

    A widely tunable mode-locked all-fiberized Yb-doped fiber laser with near-transform-limited spectrum linewidth is used. It consists of a tunable fiber Bragg grating (TFBG) and a fiber-coupled LiNbO phase modulator (PM) in a linear cavity. The TFBG is used to achieve tunable emission wavelength,...

    We numerically simulated the pulse formation in a femtosecond Ti:sapphire laser and investigated the effect of a discrete distribution of dispersion and self-phase modulation. It was found that the discreteness in an actual femtosecond laser leads to pulse broadening and deviation of the pulse...
