The Attosecond Revolution

P.B. Corkum and Zenghu Chang

After years of exploration, researchers have discovered that pushing the limits of nonlinear optics allows them to produce ultra-short XUV laser pulses.

Hubble’s Final Servicing Mission

Scientists predict that this last round of repairs will finally allow astronomers to realize the full potential of the orbiting telescope.

Microspiral Resonators for Integrated Photonics

Microspiral resonators allow for unidirectional lasing and the direct coupling of light to the device’s microcavity—two characteristics that aren’t possible with conventional microresonators.

Adaptive-Focus Lenses

Researchers have recently demonstrated various approaches for constructing practical, compact adaptive-focus lenses. This article summarizes the advantages and drawbacks of each.
