Credible (and Edible) Lasers: The Life of Arthur L. Schawlow

Patricia Daukantas

Arthur L. Schawlow was truly a one-of-a-kind scientist and human being. Known for his gentle spirit, his sense of humor and his scientific creativity, he was the only Nobel Prize winner to have served as an OSA president. OPN examines... more>>


Ultrahigh-Speed Optical Processing Using Space-Time Duality

Mark A. Foster, Reza Salem and Alexander L. Gaeta

Temporal all-optical processing systems—which are based on the space-time duality of light—provide a practical approach for meeting the bandwidth demands of next-generation ultrahigh-speed technologies. more>>

In-Fiber Acousto-Optic Devices for Laser Applications

Christian Cuadrado-Laborde, Antonio Díez, Miguel V. Andrés, José L. Cruz and Miguel Bello-Jiménez

These authors review in-fiber acousto-optic devices that have demonstrated new possibilities for the control of Q-switched distributed feedback and mode-locked all-fiber lasers—in other words, tools for using sound to control light. more>>

Applied Optics and the Early Days of the Laser

John N. Howard

Prompted by the complaints of the so-called “Subversive Optics Society” in the late 1950s, OSA launched a new journal in 1962 to represent modern topics in optics. Due to fortuitous timing—and a highly competent managing editor—Applied Optics was able to cover the most current topic imaginable long before its competition: the laser. more>>


Using Satellite Maps to Aid Japan

Yvonne Carts-Powell

In response to explosions at the Fukushima Nuclear Power Plant in the week after Japan’s 9.0-magnitude earthquake and tsunami on March 11, mapmakers at the Rochester Institute of Technology quickly made maps from satellite images to help emergency responders. more>>

Pop Culture Crimes against Lasers (and Other Optics)

Stephen R. Wilk

With the laser into its 51st year of existence, filmmakers and TV producers have had a long time to master the fundamentals of lasers and other optical concepts. But optics unfortunately remains victim to the ever-tempting appeal of drama over reality. more>>

Evolving CMOS Technology for High-Performance Single-Photon Detection

Edoardo Charbon

For decades, solid-state detectors could capture individual photons. This is now possible to do using avalanche photodiodes. So-called single-photon avalanche diodes (SPADs) are avalanche photodiodes biased above breakdown in Geiger mode and fabricated using CMOS processes. more>>
