Scientists studying a mysterious effect called cosmic birefringence—a subtle twist in the polarization of the universe’s ...

Light is an unusually rich carrier of information. Its direction of travel, wavelength, and polarization can all be used to ...

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 ...

Terahertz (THz) waves, situated between the microwave and infrared regions of the electromagnetic spectrum, have drawn considerable attention over the past two decades. Researchers from the Aerospace ...

Controlling both the state and degree of polarization of light is a long-standing challenge in optics. While metasurfaces offer compact, high-resolution control over wavefronts, most existing designs ...

Scientists studying asteroids found that two seemingly unrelated types share a strange dusty coating of troilite. By using polarization of light instead of traditional spectra, they uncovered evidence ...

The polarization splitting prism is used to separate the horizontal polarization and vertical polarization of a beam of light, and the transmittance ratio of P light and S light is greater than 1000, ...

Researchers created a technique to reduce uncertainty in cosmic birefringence measurements, resolving a key phase ambiguity and improving future studies of fundamental physics.
