Mid- and far-infrared birefringent crystals are key functional materials for polarization control, laser technologies, and ...

In 2020, an interesting new phenomenon called cosmic birefringence was reported from the cosmic microwave background (CMB) polarization data. Polarization describes light waves oscillating ...

Left: sketch of the working principle of the all-optical modulation of light polarization. The dielectric metasurface is illuminated by an intense laser pulse (“pump”, depicted as the purple beam), ...

A team of researchers studying the uncertainties associated with a phenomenon known as cosmic birefringence has developed a method to reduce uncertainties in its observational measurements, according ...
