Supercontinuum generation is one of the most spectacular and visually perceptible nonlinear effects produced by the propagation of intense laser pulses in a transparent nonlinear medium. Since its discovery in the early years of nonlinear optics, supercontinuum generation has continuously attracted a great deal of scientific and technological interest.
Supercontinuum light represents a unique and versatile source of ultra-broadband radiation with high power spectral density and coherence potentially equivalent to a white-light laser. It now routinely finds numerous applications in very diverse fields of modern optical science, ranging from frequency metrology and the generation of few-optical-cycle pulses to optical sensing and imaging. The steady technological advances in the development of novel pump laser sources, in the design of optical fibers and waveguides, as well as the availability of highly nonlinear materials, continue to foster numerous studies on supercontinuum generation in various nonlinear media, and in various parts of the optical spectrum.
The purpose of this feature is to bring together the latest developments in supercontinuum generation in both confined and bulk geometries, which, although sharing some common features, are often considered independent research areas due to differences in the underlying physics.
Topics include, but are not limited to, experimental, theoretical, and numerical studies of supercontinuum generation in optical fibers, waveguides and in bulk nonlinear media (solids, liquids and gases).
All papers need to present original, previously unpublished work, and will be subject to the normal standards and peer-review process of the journal. Manuscripts must be prepared according to the usual guidelines for submission to JOSA B and must be uploaded through OSA's electronic submission system. When submitting, please specify that the manuscript is for the Supercontinuum Generation feature issue (choose from the drop-down menu).
