CREOL Research Explores How Partially Coherent Light Could Transform Optical Communications
Featured on the cover of Optics & Photonics News, the article highlights how an emerging approach called structured coherence could improve optical communications, computing, and information processing.
A new feature article by researchers from CREOL, the College of Optics and Photonics at the University of Central Florida, has been selected as the cover story for the latest issue of Optics & Photonics News (OPN, the monthly news and feature magazine published by Optica – formerly OSA), highlighting an emerging area of research that could reshape how information is transmitted and processed using light.
The article, Taking Advantage of Structured Coherence, explores how partially coherent light, once considered less useful than laser light for advanced technologies, is revealing surprising advantages for optical communications, photonic computing, and information processing
"We are very happy that OPN selected our article for the cover. In our article we alert the optics community to some very recent exciting developments spearheaded by CREOL in one of the oldest branches of optics," said Professor Abouraddy.
The work is led by Professor Ayman Abouraddy of CREOL in collaboration with Mitchell Harling and Professor Kimani Toussaint Jr. of Brown University, and Abbas Shiri, a recent CREOL doctoral graduate.
Most people are familiar with lasers, which produce highly ordered, or coherent, light. While coherent light has powered decades of advances in communications, manufacturing, and imaging, researchers are now discovering that light with a controlled amount of randomness, known as partially coherent light, can sometimes perform tasks that fully coherent light cannot.
The team’s research focuses on a concept called structured coherence, which treats light as a collection of stable optical modes whose relationships can be carefully engineered. Rather than viewing partial coherence as a limitation, the researchers demonstrate that it can become a valuable resource for encoding and transmitting information.
One of the most exciting findings is that information encoded in a property known as coherence rank remains intact even when light passes through highly scattering environments that would normally scramble conventional optical signals. This approach could one day enable more reliable optical communication systems in challenging conditions without requiring complex adaptive correction techniques.
Beyond communications, the researchers believe structured coherence could play an important role in future integrated photonic technologies, including optical computing, cryptography, and next-generation information processing systems. As photonic chips continue to become more sophisticated, they may provide the ideal platform for harnessing these newly discovered advantages of partially coherent light.
