Soliton pulse compression in dispersion-decreasing fiber

Ultrashort soliton generation through higher-order soliton compression in a nonlinear optical loop mirror constructed from dispersion-decreasing fiber

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...

Comblike dispersion-profiled fiber for soliton pulse train generation.

A novel optical fiber [comblike dispersion-profiled fiber (CDPF)] that consists of a chain of alternating segments of standard telecommunication fiber and dispersion-shifted fiber is proposed for the generation of a soliton pulse train based on nonlinear transformation of an optical beat signal. A totally integrated all-optical fiber source of a 59.1-GHz train of 2.2-ps solitons is demonstrated...

Nonlinear pulse propagation in dispersion decreasing fibers

By numerically solving the nonlinear Schrodinger equation, we analyze pulse propagation through dispersion decreasing optical fibers (DDFs) in which the core radius varies along the length of the fiber; this in turn leads to a variation of dispersion as well as mode effective area along the length of the fiber. We calculate an optimum core radius profile required to create a local balance betwe...

Theory of parabolic pulse propagation in nonlinear dispersion decreasing optical fiber amplifiers

Parabolic pulse generation in a dispersion-decreasing solid-core photonic bandgap Bragg fiber

We analyze the interplay of nonlinearity and dispersion in a dispersion-decreasing photonic bandgap Bragg fiber as a new platform for generating parabolic pulses. A suitably designed linearly tapered, low-index-contrast, solid-core Bragg fiber – amenable to fabrication by conventional modified chemical vapor deposition technology – is shown to yield stable parabolic pulses. The fiber design was...
