Cavity Solitons
In this chapter we describe the topic of cavity solitons in the framework of the general area of optical pattern formation. We illustrate how one can generate and control them; we compare them with standard sp...

Low-energy switch based on a cavity soliton laser
We show that the position of a soliton in a cavity soliton laser can be controlled by injecting incoherent or coherent beams close to the soliton. The interaction between the CS and the injected beam can be at...

Instabilities for a coherently driven Fabry-Perot cavity with a very thin absorber
We study the multi-longitudinal mode instability in purely absorptive optical bistability in the limit of nonlinear absorber much thinner than one wavelength. Under that assumption the dynamical equations are ...

Self–propelled soliton collisions in a semiconductor cavity soliton laser
Spontaneous soliton motion has been demonstrated in different systems supporting cavity solitons. Here we consider the case of a semiconductor laser with an intracavity saturable absorber, and study the intera...

Intracoronary optical coherence tomography, basic theory and image acquisition techniques
Optical coherence tomography (OCT) imaging is showing great potential as an alternative or complementary tool to intravascular ultrasound (IVUS) for aiding in stent procedures and future diagnosis/treatment of...

Self-pulsing localized structures in a laser with saturable absorber
We consider a broad area heterostructured semiconductor laser with an integrated saturable absorber in a monolithic configuration. We extend beyond the single-longitudinal mode approximation a model already u...

Spontaneously moving solitons in a cavity soliton laser with circular section
We show that in a cavity soliton laser based on a VCSEL with a saturable absorber the solitons can spontaneously move if the ratio of the carrier lifetimes in the amplifier and in the absorber takes appropria...

Static and dynamic properties of cavity solitons in VCSELs with optical injection
The static and dynamical properties of cavity solitons in a vertical cavity surface emitting laser with optical injection are investigated. Analytical results about the instabilities affecting the homogeneous...

Comparison of different switching techniques in a cavity soliton laser
We compare three different switching techniques for the control of cavity solitons in a VCSEL-based cavity soliton laser, one incoherent and the other two semicoherent with different injection frequencies. We ...

Cavity Solitons in Semiconductor Devices
Cavity solitons represent a class of dissipative solitons which are generated inside an optical resonator. They have attracted considerable interest in the recent years due to their possible application to opt...

Effects of carrier radiative recombination on a VCSEL-based cavity soliton laser
A vertical cavity surface emitting laser with saturable absorber can work as a cavity soliton laser. We show that the properties of the system are deeply influenced by the radiative recombination of carriers. ...

Cavity soliton laser based on VCSEL with saturable absorber
We study theoretically a broad-area vertical cavity surface emitting laser (VCSEL) with a saturable absorber. We show numerically the presence of cavity solitons in the system: they exist as solitary structure...

Intravascular ultrasound insights into plaque composition
Previous studies correlating histomorphology with 20–30 MHz-derived intravascular ultrasound (IVUS) images showed that IVUS provides to some extent qualitative information on plaque composition. IVUS imaging ...

Fluid geochemistry of Montserrat Island, West Indies
Two geochemical surveys carried out in March 1991 and September 1992 revealed the existence of a hydrothermal system in the southern portion of Montserrat Island, below Soufrière Hills Volcano. This conclusio...

Value of low-dose echodobutamine in the diagnosis of patency of the infarct related coronary artery
The resumption of contractility of asynergic segments in survivors after acute myocardial infarction (AMI) may be detected in viable myocardial areas. We have correlated the detection of viable myocardium, ass...

Generation of nonclassical states by nonlinear optical systems
We review the main results obtained recently by our group in the field of quantum noise reduction in nonlinear optical systems. We illustrate the possibility of obtaining significant effects in degenerate para...

Quantum Noise Reduction and Instabilities in Nondegenerate Four-Wave-Mixing
Four-wave-mixing (FWM) is one of the basic mechanisms in nonlinear optics. We consider the interaction of a pump field of frequency ω l and two signal fields (or more precisely, a signal and an id...
