This year, as the laser celebrates its 50th anniversary, a field that was made possible through laser technology reaches an important milestone as well. Over the past 40 years, optical manipulation research has deepened our understanding of physics and biology, and it has yielded the optical-tweezer technique that is used across all the sciences.by David McGloin and Jonathan P. Reid
Low-cost semiconductor lasers power the shortest networks in the data center and the long-haul links that speed information around the globe. Today, lasers are integrated into photonic circuitry and even optical cables.by Patricia Daukantas
Hermann von Helmholtz was many things to many people: physicist, teacher, medical doctor, aesthete and more. He drew on his extensive knowledge of many fields to invent the ophthalmoscope—a device that revolutionized ophthalmology—when he was just 29 years old.by Barry R. Masters
Diffractive waveplates exhibit the high diffraction efficiency of Bragg gratings in micron-thick material layers.by Nelson V. Tabiryan, Sarik R. Nersisyan, Diane M. Steeves and Brian R. Kimball
Departments and Columns
In 2008, an optics professor at the University of Chile and ten pedagogy students began work on a program to educate elementary school children about light and optics. A marvelous voyage had begun.
From antiquity to C.V. Raman’s time to today, India has evolved to become a leader in optical research and industry.
Long before Ted Maiman made the first ruby laser work, the concept of directed light had already entered the public consciousness—through all manner of sci-fi ray guns, “blasters,” and hand-held beams.
An adaptive liquid crystal (LC) diffractive lens developed at the University of Arizona (U.S.A.) focuses with high efficiency and zooms with millisecond-fast switching times.
Our conversation with Philippe Keryer, executive VP at Alcatel-Lucent and OFC/NFOEC plenary speaker.
In the late 1800s, the University of Nebraska became the first school west of the Mississippi to award a doctoral degree. It also gave optics three bright stars and early leaders.
Our conversation with Hideo Myahara, president, National Institute of Information & Communications Technology and OFC/NFOEC plenary session keynote.
To investigate why some insects can survive freezing, while others can’t, researchers filmed the formation and spread of ice in real time as fly larvae froze using high-energy X-rays from the Advanced Photon Source (APS).
