Accumulated photon echo experiments in erbium-doped optical fibers are reviewed. The experiments demonstrate the advantage of the single-mode optical fibers for investigations of resonant coherent effects. A theoretical analysis of the accumulated ec

Subpicosecond optical pulses propagating in single-mode fibers are severely distorted by third-order dispersion even at the fiber's zero-dispersion wavelength ( lambda /sub 0/). Using cross-correlation techniques, the authors measured the broadening

Future electronic and photonic devices and integrated circuits will be utilizing III–V compound semiconductors and their alloys. The sensitivity of these materials to electrical overstress or electrostatic discharge is crucial to their performance

Persistent Spectral Hole-Burning: Science and Applications.
Recently, interest in photon echo has been revived because of its potential application in time-domain optical memories1. Several demonstrations have been reported in gases and also bulk organic and inorganic materials at cryogenic temperatures2-4. I

We report the observation of a new interference phenomenon in photon echo experiments which are performed in an optical fiber. This phenomenon is unique to the guided wave environment and is the result of propagation in an optically thick absorber. T

Optical fibers have proven to be one of the most important nonlinear media, even though in most cases the nonlinearity exploited is the notoriously weak Kerr effect of the silica-based fiber. By using doped fibers, new, stronger nonlinearities are po

Electroluminescence in semiconductors is usually produced by recombination of electron-hole pairs either directly or via recombination centers. Another possible mechanism is the excitation of a center from its ground state to an excited state via dir

The emission spectra of the following molecular centers in ZnS lumocen films have been studied over the range from 3500A to 1.1µ and have been related whenever possible, to known energy level schemes: PrF 3 , NdF 3 , SmF 3 , TbF 3 , DyF 3 , ErF 3 ,
