It has been known for centuries that light exhibits wave-like behavior in certain situations. Some materials are able to rotate the polarization, i.e. the direction of oscillation, of the light wave ...

Photonics is the study of the generation, detection, and manipulation of light waves in the form of photons. One interesting property of light is polarization, defined by its electric and magnetic ...

Bengaluru: Indian Institute of Science (IISc) researchers have developed a non-invasive technique to measure blood glucose levels using polarised light and sound waves, offering hope for people with ...
