Stationary rescaled pulse in alternately concatenated fibers withO(1)-accumulated nonlinear perturbations

Abstract

Pulse propagation in a transmission line comprising alternately concatenated fibers with O1-accumulated perturbations of self-phase modulation and anomalous dispersion is studied. In such a line, a pulse compression process is inevitable. In certain conditions, we have found that a compressed pulse can be rescaled to the initial pulse, and hence that there exists a stationary rescaled pulse (SRP), which is distinct from other nonlinear stationary pulses such as the guiding-center, dispersion-managed, or split-step solitons. The properties of SRP are studied. We apply the rescaling to the transmission line rather than to the pulse, and we experimentally observe a SRP in a periodically rescaled transmission line.

Pulse compression techniques using highly nonlinear fibers

“…Sect. 5 is devoted to review the technologies of a pulse compression fiber so-called comb-like profiled fiber (CPF) [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] that consists of alternate concatenations of HNLF and SMF. The features, the design guideline, and experimental results of optical pulse compression using CPFs are summarized, and we show that CPF is the most suitable for realizing a truly practical and flexible optical pulse source based on fiber-based pulse compressor.…”

“…On the other hand, a coarse-step CPF, in which a steep compression process occurs, exhibits different features from the fine-step one. In fact, the authors and their collaborators have discovered a new class of nonlinear stationary pulse existing in the CPF pulse compression scheme, that is called "the stationary rescaled pulse (SRP)" [25,27]. SRP is interesting in that highly steep optical pulse compression beyond the ASC regime can be realized in a quite systematic manner.…”

“…Obviously, such a procedure was neither systematic nor efficient to obtain an optimized design for a CPF. Meanwhile, a unique nonlinear stationary pulse propagating through a CPF, that is what we call "the stationary rescaled pulse (SRP)", was discovered to be applied to the design of CPF [25]. The discovery of the SRP propagation has indeed enabled systematic design of a CPF.…”

Dynamics of Optical Pulses Propagating in Fibers with Variable Dispersion

“…Nonlinear pulse propagation in periodic transmission lines with multisegmented fibers was investigated extensively. The dispersion managed soliton (Malomed, 2006;Smith et al, 1996), split-step soliton (Driben et al, 2000), and stationary rescaled pulse (Inoue et al, 2005) have been discovered. The studies were focused mainly on the stability of solitons.…”
