Cover Story

A game of billiards with Spatial-Solitary Waves in KTP

William E. Torruellas and Lluis Torner

A RADICALLY NEW WAY TO THINK OF THE PROBLEM OF MULTI-DIMENSIONAL SELF-TRAPPING HAS COME TO LIGHT IN QUADRATIC NONLINEAR IN TERACTIONS. IN THIS ARTICLE, THE AUTHORS NOT ONLY SHOW THAT THE DIFFRACTION IN SPATIAL WALKOFF CAN BE DEFEATED... more>>

Features

Automated Dna Sequencers: The Next Generation

David Rank

Optically detected DNA sequencing technologies facilitate sequencing the 3 billion base pairs of the human genome. Faster, higher throughput optically detected electrophoresis instrumentation will be necessary to bring the cost of sequencing the entire genome down and to complete the project by 2005. more>>


Emerging Optical Biomedical Imaging Techniques

S.K. Gayen and R. R. Alfano

Since Victorian times, the search has been on for a noninvasive way to peer inside the human body using light. Today’s researchers don’t have the perfect solution yet. This article explores the optical imaging techniques that look most promising. more>>


Measuring Fast Pulses With Slow Detectors

Ian Walmsley and Rick Trebino

It is now possible to measure the complete temporal intensity and phase of even the shortest of optical pulses. The authors describe the revolution in measurement techniques that have made this possible. more>>
