Periodic structures, such as those found in photonic crystals, can generate iridescent colors. They allow some objects in nature, including opals, to display gleaming colors, even in the absence of pigment. Electromagnetic theory allows the phenomenon to be investigated through modeling.

Nematicons are self-trapped light beams in nematic liquid crystalline systems. Thanks to their optically nonlinear, saturable, nonlocal and nonresonant response, they enable light to self-confine and guide additional optical signals, making them an ideal testbed for applications in all-optical information processing.

A High School Optics Lab Offers Lessons in Learning
The Thomas Jefferson High School for Science and Technology, a magnet school in the Virginia suburbs ofWashington, D.C., offers one of the only optics and modern physics laboratories for high school students in the United States.
How to Use OASIS
The submissions process for OSA conferences was revamped in August 2002 with the launch of OASIS, the Online Abstract Submission and Invitation System. OASIS is an abstract service provider that can be used in several stages of the electronic paper submission and review process.
Fun with Photonics: An Experiment with Polariscopes
OSA Fellow Keigo Iizuka developed the hands-on learning program, “Fun with Photonics,” to spark interest in optics among members of the general public. The series was first presented to automotive engineers at Omron Corporation, Komaki City, Japan. In the fourth installment, Iizuka describes how to improvise a polariscope.
From Optics to Outer Space: OSA Fellow Ellen Ochoa
OSA Fellow Ellen Ochoa is the first Hispanic woman astronaut, which means she is a very public figure. Originally from rolling hills just east of San Diego, she has spent nearly 1,000 hours in space.
A Career as a Consultant: Making the Change
In the first of a two-part series, consultant Jennifer D.T. Kruschwitz, an engineer specialized in optical coatings, offers advice on how to set up your own consulting business.
George Ellery Hale: Master Builder for Astrophysics
This is the third in a series of articles highlighting outstanding personalities in the history of optical science. Astrophysicist George Ellery Hale (1868-1938) was one of OSA’s first honorary members.
