“…2, but now we investigate different lengths of fiber and allow for nonuniform changes of and along the fiber, that is, different profiles of and [4]. Our simulations indicate that the shortest fiber length over which the maximum compression can be achieved requires constant effective gain along the fiber [19], [20]. In its dimensionless form, this condition can be written as (2) where is the initial soliton width and is the position along the optimized fiber.…”

Abstract-We investigate numerically the compression of femtosecond solitons at 1.55-m wavelength propagating in holey fibers which exhibit simultaneously decreasing dispersion and effective mode area. We determine optimal values of holey fiber parameters and fiber lengths for soliton compression in the adiabatic and nonadiabatic regimes. Compression factors in excess of ten are found for fibers as short as a few meters.Index Terms-Fiber design and fabrication, microstructure optical fibers, pulse compression methods.

“…From the point of view of telecom applications, XPolM-MI can be an essential source of nonlinear impairments for WDM systems with polarization interleaving or polarization multiplexing [42][43][44][45]. Also on a more fundamental level, MI is a generic nonlinear process that occurs in many areas, and it is at the origin of very important fundamental phenomena, such as optical soliton generation [46,47], supercontinuum generation [48], and rogue wave formation [29,30,[49][50][51].…”

Polarization modulation instability in a Manakov fiber system

The Manakov model is the simplest multicomponent model of nonlinear wave theory: It describes elementary stable soliton propagation and multisoliton solutions, and it applies to nonlinear optics, hydrodynamics, and Bose-Einstein condensates. It is also of fundamental interest as an asymptotic model in the context of the widely used wavelength-division-multiplexed optical fiber transmission systems. However, although its physical relevance was confirmed by the experimental observation of Manakov (vector) solitons in a planar waveguide in 1996, there have in fact been no quantitative experiments confirming its validity for nonlinear dynamics other than soliton formation. Here, we report experiments in optical fiber that provide evidence of passband and baseband polarization modulation instabilities in a defocusing Manakov system. In the spontaneous regime, we also reveal a unique saturation effect as the pump power increases. We anticipate that such observations may impact the application of this minimal model to describe and understand more complicated phenomena in nature, such as the formation of extreme waves in multicomponent systems.

“…Some techniques, such as the nonlinear intensity discrimination technique [2,3] can reduce the pedestals, but typically energy is wasted. Adiabatic soliton compression typically utilizes a dispersion map with monotonically decreasing dispersion along the propagation direction, z, and is formally equivalent to distributed amplification [4,5]. If the dispersion varies slowly enough, the soliton self-adjusts to maintain the balance between dispersion and nonlinearity (by reducing its pulse width; hence the term adiabatic compression) [6].…”

We demonstrate almost chirp-and pedestal-free optical pulse compression in a nonlinear fiber Bragg grating with exponentially decreasing dispersion. The exponential dispersion profile can be well-approximated by a few gratings with different constant dispersions. The required number of sections is proportional to the compression ratio, but inversely proportional to the initial chirp value. We propose a compact pulse compression scheme, which consists of a linear and nonlinear grating, to effectively compress both hyperbolic secant and Gaussian shaped pulses. Nearly transform-limited pulses with a negligibly small pedestal can be achieved.
