The Magical World of Photonic Metamaterials

Metamaterials have opened a world of new possibilities that would have seemed like science fiction a decade ago, including subwavelength imaging, super lenses, perfect lenses and cloaking.

Coaxial Holographic Data Recording

Holographic memory surpasses all other optical memories in both data density and data-transfer rate—but its development has lagged behind disk technologies. The coaxial recording method may enable holography to become an integral part of the optical storage marketplace of the future.

Optical Interference Coatings: Three Manufacturing Problems

How can one produce a thin-film filter that reproduces irregular spectral transmittance and reflectance curves for near-normal incident light? How about filters intended for use at oblique angles of incidence? These problems were part of a unique thin-film manufacturing competition at OSA’s Topical Meeting on Optical Interference Coatings.

Putting Plasmons Through Their Paces

Researchers at the University of Pennsylvania have found that a number of unusual effects are possible when light is guided along a chain of metal nanoparticles—including the generation of wave packets that move faster than the speed of light.

The History of OSA
A Profile of Walter Baird

Walter Scott Baird is one of the unsung heroes of OSA. Although he never served as an OSA president or won any of the Society’s awards, he probably did more to bring the Society in step with modern times than any other individual.
