“…Though "incoherent" switching was obtained before in driven cavity or feedback systems (Maywar et al (2000); Schäpers et al (2000Schäpers et al ( , 2002; ; Pesch et al (2005); Barbay et al (2006)), the main route for control there is the phase of the WB with respect to the HB (and thus the CS) (Brambilla et al (1996); Spinelli et al (1998); Barland et al (2002); Hachair et al (2005)) leading to constructive or destructive interference and thus controlling locally the amplitude of the intra-cavity field. The insensitivity of the switching in CSL to phase is probably one of their major advantages in applications though it is probably fair to say that many aspects of the switching process and potentials for optimization are not well understood at this point (see also Sec.…”

We review the properties of optical spatial dissipative solitons (SDS). These are stable, self-localized optical excitations sitting on a uniform, or quasi-uniform, background in a dissipative environment like a nonlinear optical cavity. Indeed in optics they are often termed 'cavity solitons'. We discuss their dynamics and interactions in both ideal and imperfect systems, making comparison with experiments. SDS in lasers offer important advantages for applications. We review candidate schemes and the tremendous recent progress in semiconductor-based cavity soliton lasers. We examine SDS in periodic structures, and we show how SDS can be quantitatively related to the locking of fronts. We conclude with an assessment of potential applications of SDS in photonics, arguing that best use of their particular features is made by exploiting their mobility, e.g. in all-optical delay lines.

“…More recently attention has focused on distributed feedback semiconductor optical amplifiers (DFBSOAs). Maywar et al demonstrated 1.3-1.55 |Jim wavelength conversion [15] and optical flipflop operation [16] under simultaneous injection of two optical signals at different wavelengths into a DFBSOA working in transmission.…”

Switching of a signal beam by another control beam at different wavelength is demonstrated experimentally using the optical bistability occurring in a 1.55 |Jim-distributed feedback semiconductor optical amplifier (DFBSOA) working in reflection. Counterclockwise (S-shaped) and reverse (clockwise) bistability are observed in the output of the control and the signal beam respectively, as the power of the input control signal is increased. With this technique an optical signal can be set in either of the optical input wavelengths by appropriate choice of the powers of the input signals. The switching properties of the DFBSOA are studied experimentally as the applied bias current is increased from below to above threshold and for different levels of optical power in the signal beam and different wavelength detunings between both input signals. Higher on-off extinction ratios, wider bistable loops and lower input power requirements for switching are obtained when the DFBSOA is operated slightly above its threshold value.

“…On the other hand, there are electrical and optical bias techniques used to shorten the effective carrier lifetime of SLA's down to 10 ps [17]. Hence, we expect that these techniques permit such devices to find applications in high-speed communications.…”

In this article, we have proposed a procedure to analyze transient response of bistable distributed feedback semiconductor laser amplifiers. The results of the analysis show that among bistable distributed feedback semiconductor laser amplifiers with uniform, quarter wavelength phase-shifted, and tapered gratings, the latter has the best switching behavior. This behavior includes relaxation oscillation, switchingon time, and switching-off time of the output pulse for an input pulse. Transfer matrix and the finite difference time-domain methods are utilized for numerical simulation.
