Effects of Nonlinear Chirp on the Self-Phase Modulation of Ultrashort Optical Pulses
نویسندگان
چکیده
In this article, we analytically investigate the spectral broadening by self-phase modulation of strongly chirped optical pulses. The dispersion due to the nonlinear optical process is expressed as functions of a linear and a nonlinear initial chirp. As a result, it is found that the third-order dispersion strongly depends on the initial linear chirp and the nonlinearity for self-phase modulation.

Comparison of ultrashort-pulse frequency-resolved-optical-gating traces for three common beam geometries
We recently introduced frequency-resolved optical gating (FROG), a technique for measuring the intensity and phase of an individual, arbitrary, ultrashort laser pulse. FROG can use almost any instantaneous optical nonlinearity, with the most common geometries being polarization gate, self-diffraction, and secondharmonic generation. The experimentally generated FROG trace is intuitive, visually ...
متن کاملSpectral Broadening of Ultrashort Optical Pulses in Nonlinear Photonic Crystal Fiber
A variety of nonlinear effects such as self – phase modulation (SPM) lead to spectral broadening of optical pulses. In the case of intense ultrashort pulses, when SPM is accompanied by other nonlinear processes such as stimulated Raman scattering and four-wave mixing, it leads to an extreme spectral broadening referred to as supercontinuum. In this paper, we demonstrate the effects of various n...
متن کاملPhase retrieval and compression of low-power white-light pulses
We characterize and compress sub-nJ visible white-light continuum (WLC) pulses generated by self-phase modulation in yttrium aluminium garnet. The spectral phase is retrieved by spectrally resolving the transient reflectivity from an optically-excited transition metal oxide. This measured phase is compensated by applying the appropriate distortion to a deformable mirror. By comparing the respon...

A novel technique to generate ultrashort fundamental solitons is proposed and demonstrated numerically. The technique utilizes both the multisoliton pulse-compression effect and the switching characteristics of a nonlinear optical loop mirror constructed from dispersion-decreasing fiber. We show that, in contrast to the conventional soliton-effect pulse compression in which compressed pulses ar...
