The propagation of optical pulses is considered at the zero-dispersion wavelength of
nonlinear dispersive fibers. Even in the absence of group-velocity (first-order) dispersion …

Using computer simulations, we examine the effects of higher-order dispersive and
nonlinear propagation processes on the spectral and time development of ultrashort, high …

Pulse propagation in optical fibers is considered after including the effects of chromatic
dispersion and nonlinearity. To estimate the extent of pulse broadening, an analytic …

We report the narrowing of pulses, initially 7 psec FWHM, to widths as small as 0.26 psec by
various lengths, short relative to the soliton period, of single-mode, low-loss optical fiber …

It is demonstrated that for an optical pulse propagating along an optical fiber the rms pulse
width varies parabolically with distance, irrespective of initial pulse form and frequency chirp …

The technique of frequency-resolved optical gating is used to characterize the intensity and
the phase of picosecond pulses after propagation through 700 m of fiber at close to the zero …

Pulses launched with their central wavelength in the region of the minimum-dispersion
wavelength of a single-mode optical fiber exhibit a distinct spectral splitting due to the …

We experimentally observed transmission of “negative pulses” through a single mode
optical fiber in conditions where self-phase modulation, due to self induced variations of …

Nonlinear pulse propagation at the zero group-dispersion wavelength is studied analytically.
It is discovered that, after the characteristic initial frequency splitting, evolution of the pulse …

For nonlinear short-pulse propagation in long optical fibers, the conventional static
approximation of the nonlinear terms in the wave equation must be extended to include the …
