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 ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

A domestic research team has implemented the world’s first ultracompact spectrometer that can simultaneously analyze the color and rotation direction of light. Because this technology can replace ...

NASA's newest spacecraft aimed at studying the sun have captured a colorful "rainbow" in the warm glow of zodiacal light observed above Earth. The PUNCH (Polarimeter to Unify the Corona and ...
