A new type of semiconductor laser is studied, in which injected carriers in the active region
are quantum mechanically confined in localized finite self-assembled wire-like quantumdash
(Qdash) structures that are varied in sizes and compositions. Effects of such carrier
distribution and quasi three-dimensional density of states contribute to a quasisupercontinuum
interband lasing characteristics, which is a new laser design platform as
compared to continuous broad emission spectrum generated by nonlinear media pumped
with ultrashort laser pulse....
The book embraces a wide spectrum of problems falling under the concepts of "Quantum optics" and "Laser experiments". These actively developing branches of physics are of great significance both for theoretical understanding of the quantum nature of optical phenomena and for practical applications.

Optical Switching Networks describes all the major switching paradigms developed for
modern optical networks, discussing their operation, advantages, disadvantages, and
implementation. Following a review of the evolution of optical wavelength division
multiplexing (WDM) networks, an overview of the future of optical networks is set out.
This volume includes papers presented at the XXII Solvay Conference on Physics, which took
place from the 24 to 29 November 2001 in the European Culture Centre of Delphi. The
Castle of Lamia hosted the events of the last day.
The Physics of Communication was the selected theme of the conference. The 5 sessions
reflected present challenging issues, namely Decoherence and Irreversibility, Non-locality and
Superluminosity, Photonics, Quantum Information and Communication, Quantum
