Combination of metamaterials and singular optics fueling research innovation

Sep 12, 2012
Research being conducted in Litchinitser's lab could be used to develop new technology designed to process greater amounts of information quicker than traditional microchips.

(Phys.org)—Will humans ever control lightning? Could we make the invisible visible, and vice versa?

It's those questions and more that researchers such as Natalia Litchinitser, an associate professor of electrical engineering at the University at Buffalo, are exploring in the evolving field of modern optics.

Optics, or the science of light, is a centuries-old branch of physics that examines the properties and behavior of light, including its interaction with matter, and the instruments that use and detect it.

Modern optics refers to advancements starting in the 2oth century to present. Examples include high-powered lasers, light-emitting diodes (LEDs) and .

The synergy of two branches of modern optics—metamaterials and singular optics—is fueling even more , Litchinitser wrote in an essay published Aug. 31 in the journal Science. The essay can be found at http://www.sciencemag.org.

"Metamaterials and singular optics are two fascinating branches of modern optics that until recently were rapidly developing in parallel yet independently," Litchinitser writes.

The field of metamaterials focuses on the development of manmade structures that exhibit optical, acoustical and not found in nature. They have many potential uses, such as creating high-resolution imaging devices and improved sensors. They're also used to make that might someday render objects invisible.

Singular optics, meanwhile, centers on manipulating —usually with a laser and other components—into a corkscrew pattern that resembles a tornado's shape. The effect, which leaves a dark hole in the light's center, is called an optical .

Like metamaterials, singular optics has many potential applications, including improving bandwidth efficiency and data processing rates. It also may enable researchers to build that, when pointed into a storm cloud, could control lightning to avoid potential strikes with airports, power plants or other sensitive structures.

A small but growing number of researchers began combining elements of metamaterials and singular optics last decade with the financial support of the Department of Defense, NASA and other federal agencies, Litchinitser said.

Litchinitser's research received a boost last year when the Defense Department awarded her and fellow researchers Alexander N. Cartwright and Grover Swartzlander a $1.4 million grant. A UB professor of , Cartwright is UB's vice president for research and economic development. Swartzlander is a physics professor at the Rochester Institute of Technology.

The researchers—along with a team of postgraduate, graduate and undergraduate students—are using elements of singular optics and metamaterials to develop new technology designed to process greater amounts of information quicker than traditional microchips.

The potential for metamaterials and singular optics is perhaps best summed up at the conclusion of Litchinitser's essay.

"Metamaterials are poised to bring new dimensions to the science and applications of complex light..." the essay says.
