Quantum Entanglement in Optical Fiber
Quantum entanglement is perhaps one of the deepest mysteries of quantum mechanics. Today, entangled states are part of our state-of-the-art communication systems, offering a more secure transfer of information.

Illuminating the Science of Light for Young Girls
The National Coalition of Girls’ Schools (NCGS) Science of Light workshop,funded by the OSA Foundation, took place in conjunction with the annual meeting of the NCGS last summer.
Diamond-Turned Optics Manufacturing and Precision Mechanical Metrology
Single-point diamond turning manufacturing combined with precision mechanical metrology can improve the quality of many optical systems and change the nature of the optical assembly process. The effective result is “bolt-together” optical assemblies requiring minimal alignment and no “gotchas” during final assembly.
2007 in Review: Good and Bad News for Science Policy
During the first half of 2007, Congress achieved a major victory with the passage of the America COMPETES Act, which authorized significant new investments in federal research and key science education programs. The thrill of victory was diminished by year’s end, however, when science and technology funding fell victim to budget pressures and a showdown between the White House and Congress over spending levels.
UV Lithography Makes Microparticles
A new method for making microscale particles with distinct sizes, shapes and textures combines microfluidics with phase mask lithography.
Celebrating 25 years of the Journal of Lightwave Technology
In December 2007, the IEEE/OSA Journal of Lightwave Technology celebrated its 25th anniversary. To mark the occasion, a past and present editor-in-chief share their perspectives and invite the insights of four key figures in the journal's evolution.
Swamp Optics LLC: Everything You’ve Always Wanted to Know About Ultrashort Pulses, But Were Afraid to Ask
In order to measure an event in time, you need a shorter one. So how do you measure the shortest one? This dilemma initiated a scientific odyssey that culminated in the founding of Swamp Optics.
Sound Stores Light, Briefly
A system that uses off-the-shelf components provides a way to store light as sound, briefly, in optical fiber.
