Optimal Plasmon Focusing with Spatial Polarization Engineering

Weibin Chen, Robert L. Nelson, Don C. Abeysinghe and Qiwen Zhan

Scientists can now manipulate the state of polarization across a laser beam at the wavelength scale. Such engineering allows for optimal plasmonic focusing that could be translated into efficient coupling for plasmonic circuits, high-resolution imaging, biochemical sensing and thin-film characterization.

Metamaterial-Induced Transparency: Sharp Fano Resonances and Slow Light

Inspired by the study of atomic resonances, researchers have developed a new type of metamaterial. Their work paves the way toward compact delay lines and slow-light devices.

Lasers in Paleontology

Paleontology has come a long way since early fossil-hunters roamed the Wild West at the end of the 19th century using sharp eyes, picks and shovels to excavate bones. Now, 21st century paleontologists are using lasers to record three-dimensional images of their discoveries, to analyze fossils, and to date rocks.

Robert W. Wood: The Scientist who Played with Optics

Robert Williams Wood viewed the natural world as his playground. For him, science was a highly creative endeavor to be approached with curiosity and awe. Wood was also a scientific maverick who questioned all dogmas. Above all, he was an experimentalist: He tested conclusions, built his own apparatuses, and was excited about every part of the process.
