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. more>>

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. more>>

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. more>>
