On the Shoulders of Giants
For millennia, scholars in the old and new worlds have realized that their efforts depend largely on the works of those who came before. The “eureka!” moments experienced by scientists...
Bending Light at will with Transformation Optics
Invisibility cloaks get all the publicity, but they may just be the beginning if the promise of transformation optics can be realized. The discipline could lead to smaller photonic and electronic...
High-Throughput Measurement Speeds Production of Large Optics
Dynamic laser interferometry is an established technique for measuring optical-grade surfaces in the presence of vibration and air turbulence. Unlike traditional laser interferometry, dynamic...
Back-Illuminated CMOS Image Sensors Come to the Fore
Solid-state image sensors come in two variants: CCD and CMOS. CCDs generally offer superior image quality. However, CMOS dominates in manufacturing volume because it permits an integrated solution in...

Fifty years and counting …
Looking back through photo albums, parents and relatives can “ooh” and “aah” over a baby’s milestones long after the baby has grown up, graduated from college, gotten married and had babies of his or her own. This month marks a very important birthday for the laser: On May 16, 1960, Hughes Research Laboratories physicist Theodore H. Maiman demonstrated the first ruby...

Brighter lights lead to better communications under the sea
Future oceanographic research could be done more cheaply and efficiently, thanks to a communication innovation powered by the latest LEDs and detectors. Researchers from Woods Hole Oceanographic...
Stacking ‘Lego’ blocks of light
Many of us enjoyed donning our construction hats and building little houses out of Lego blocks when we were young. Now, researchers at the University of Calgary are playing a similar game, but rather...
Liquid crystals: Size and shape matter
When it comes to liquid crystals, scientists at Texas A&M University have discovered that size and shape really matter. Dr. Zhengdong Cheng, an assistant professor of chemical engineering, and...
Designer molecules promise all-optical processing
Supporters of all-optical switching say it will allow dramatic speed increases in data communications by eliminating the need to convert photonic signals to electronic signals – and back....
Novel systems detect explosives
The need for technologies that can detect explosives with high sensitivity and from far away is as great as ever. A number of groups are working to develop such technologies. At the University of...
Light moves in not-so-mysterious ways
How can we search the Internet more quickly? How will future quantum computer networks operate? What is happening during the fast energy transfer in photosynthesis? These and many other questions...
For fast communication, divide and conquer
By splitting up one big, tough problem into many smaller and easier parts, researchers at the University of California, Davis, may have created the basis for ultrafast optical communications. Team...
Photothermal imaging detects nanorod orientation
“Fluorescence vector probes and polarization-sensitive single-molecule spectroscopies have been widely used to explore the conformation dynamics of proteins in biological systems – and an...

Lasers leap from the lab to the comics
When Ted Maiman fired up the first working laser in May 1960, it marked the beginning of a golden age of scientific research and technological innovation that continues today. See “A Trip Through the Light Fantastic,” p. 58, and “On the Shoulders of Giants,” p. 70. However, despite all of the advances brought about by and for lasers, there were other reasons to be excited...
