Light-Responsive Material Could Provide Basis for All-Optical Computing

Facebook Twitter LinkedIn Email Comments
A platform that could potentially be used for all-optical computing has been developed through a collaboration between researchers at McMaster University and the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS). The technology brings together an adaptive, light-responsive material developed by the Harvard team with light manipulation and measurement techniques performed at McMaster. The SEAS researchers developed a new material that uses reversible swelling and contracting in a hydrogel. Under low laser power, the refractive index of this material changes in...Read full article
