Identifying organic compounds with visible light

Researchers from the Universidad de Santiago de Chile and the University of Notre Dame, working with machine learning, have devised a method to identify organic compounds based on the refractive index at a single optical ...

Bending light to engineer improved optical devices and circuits

Rainbows are formed when light bends—or refracts—as it enters and exits a water droplet. The amount that the light bends depends on the color of the light, resulting in white light being separated into a beautiful spectrum ...
