Summary form only given. In recent years, there has been considerable interest in nonlinear and quantum optics of photonic bandgap structures. Some of this attention has centered on the properties of gap solitary waves, which are light pulses tuned a

Proceedings of the 1992 International Conference on Industrial Electronics, Control, Instrumentation, and Automation.
An algorithm for training multi-hidden-layer neural networks is presented. The algorithm system for fast training consists of a pseudoinverse matrix least squares procedure used incrementally to solve a nonlinear neural network, together with a preco

A hardware device for training multi-hidden-layer neural networks is presented. It is based on a recently developed training algorithm that is an alternative to backpropagation. The new algorithm employs pseudoinverse techniques and preconditioning o

Nonlinear Guided Waves and Their Applications.
We show that both the Dicke superradiance and pulse amplification in near-resonance Bragg structure can produce light localization in the bandgap of such structures. This localization is accompanied by formation of a principally new type of gap solit

We consider diffractive coupling in stimulated Raman scattering when an anti-Stokes wave co-propagates in a Raman active medium.

We have used classical dynamics to study high-field-intensity ionization of atoms for various parameters and different potentials. The numerical calculations establish evidence that the ionization probability {ital P} vanishes in the limit of large f

The conditions for a detailed experimental investigation of Dicke superradiance in the microwave region are presented. It is proposed to observe superradiant pulses from inverted populations in the Zeeman levels of atomic hydrogen in an external magn

A four-level model is solved analytically and used to show that laser induced excitation can result in population trapping in excited states under quasi-steady state conditions, even when chemical reactivity and/or dissociation occurs from higher sta

We propose a theory of quasi-continuum phenomena in unimolecular photoreactions. The theory is simple enough not to require computer implementation but is able to reproduce analytically and semi-quantitatively the results of full computer simulations
