Researchers at the University of Michigan have demonstrated the production of bright, twisted light using technology similar to an Edison light bulb. This discovery enriches our understanding of fundamental physics and paves the way for innovative applications in robotic vision systems and other fields.
Bright, twisted light can be produced with technology similar to an Edison light bulb, researchers have shown. The finding adds nuance to fundamental physics while offering a new avenue for robotic vision systems and other applications for light that traces out a helix in space.
Every object with any heat to it, including yourself, is constantly sending out photons in a spectrum tied to its temperature. When the object is the same temperature as its surroundings, it is also absorbing an equivalent amount of photons -- this is idealized as"blackbody radiation" because the color black absorbs all photon frequencies.
Typically, the shape of the object emitting the radiation doesn't get much consideration -- for most purposes , the object can be imagined as a sphere. But while shape doesn't affect the spectrum of wavelengths of the different photons, it can affect a different property: their polarization. "The advancements in physics of blackbody radiation by chiral nanostructures is central to this study. Such emitters are everywhere around us," said Nicholas Kotov, the Irving Langmuir Distinguished Professor of Chemical Sciences and Engineering, director of NSF Center of Complex Particles and Particle Systems and corresponding author of the study.
Kotov also wants to explore further into the infrared spectrum. The peak wavelength of blackbody radiation at room temperature is roughly 10,000 nanometers or 0.01 millimeters. Kotov is also the Joseph B. and Florence V. Cejka Professor of Engineering, a professor of macromolecular science and engineering and a member of U-M's Biointerfaces Institute. Lu is an incoming assistant professor of chemistry and physics at the National University of Singapore.
