The importance of implementing the Federal Technology Transfer Act

Jacob N. Erlich

Over the last 20 years, in several critical industries, there has been a substantial decline in the technological lead the United States holds over other countries. This erosion of the United States' technological advantage may be due to... more>>

Spectroscopic notation for the energy levels of helium and neon

Leon J. Radziemski

Spectroscopic notation traditionally places the electron configuration first, followed by the term symbol in some coupling scheme. more>>


Interferometer standardization assessed

Robert E. Parks

Major manufacturers of phase measuring interferometers joined Standards Committee members during the OSA Annual Meeting in Santa Clara to discuss standardization among the various instruments. As representatives from Breault Research Organization, Phase Shift Technologies, WYKO, and ZYGO described the similarities and differences in their instruments and responded to questions, members were surprised to learn of the relative similarity of data handling that already exists among the instruments. The committee was also pleased to learn that the companies are willing to work with members in furthering standardization and in writing a handbook on optical figure measurement. more>>


Curious features of nonlinear pulse propagation in single-mode optical fibers

W.J. Tomlinson

Single-mode optical fibers have been found to be an almost ideal medium for studying and using nonlinear optical phenomena, and such studies have uncovered numerous curious features. Despite steady progress in identifying new curious features, however, the current number of such features remains roughly constant, because of steady progress in converting curious features into simple features. more>>
