Electrostriction-induced acoustic effect in ultralong-distance soliton transmission systems.

The electrostriction-induced acoustic effect introduces a time-dependent index evolution for the following optical pulses and results in an additional temporal shift of solitons. The acoustic effect is incorporated into the nonlinear Schrödinger equation as a perturbative term. We investigate the evolution of timing jitter, taking into account both the Gordon-Haus and the acoustic effect contributions for a 10-Gbit/s sliding-frequency in-line-filter soliton system.

Phase-sensitive optical low-coherence reflectometry technique applied to the characterization of photonic crystal fiber properties.

Localized measurements of group-velocity dispersion and birefringence of photonic crystal fibers are achieved with a phase-sensitive optical low-coherence reflectometry technique. This technique is efficient for fiber samples no longer than 1 m. Theoretical simulations are in good agreement with experimental results.

Exact solutions for linear propagation of chirped pulses using a chirped Gauss Hermite orthogonal basis.

A generalized solution of the linear propagation equation is proposed in terms of chirped Gauss-Hermite orthogonal functions. Some well-known special cases are pointed out, and the usefulness of this approach in analyzing arbitrarily shaped chirped pulses in rapidly converging series is discussed.

Time-bandwidth product of chirped sech(2) pulses: application to phase-amplitude-coupling factor measurement.

An exact analytical expression for the time-bandwidth product DeltatDeltaf of chirped sech(2) pulses is derived. The relation can be expressed by DeltatDeltaf = 0.1786 arcosh(cosh pialpha + 2) as a function of the laser's phase-amplitude coupling factor alpha.

Phase jitter in an injection-locked semiconductor laser.

An expression for the mean-square phase jitter of an injection-locked semiconductor laser is derived. It leads to the determination of the power spectrum of the locked laser. The theoretical results are in good agreement with experimental results reported previously [IEEE J.

Analysis of frequency chirping of semiconductor lasers in the presence of optical feedback.

The frequency chirping of a single-mode semiconductor laser in the presence of optical feedback is studied by rate-equation analysis. The model includes the amplitude-phase-coupling and spectral-hole-burning effects. A simple analytical formula is obtained in the small-signal regime that shows that the amplitude-phase-coupling effect also enhances the chirp-reduction ratio and that the maximum reduction of frequency chirping can be achieved at the same time as maximum line narrowing in the in-phase condition.
