A new liquid-crystal device reflects different colors of light with increasing applied voltages, transitioning from mostly transparent to almost mirrorlike (ACS Photonics 2014, DOI: 10.1021/ph500259h) ...

(Nanowerk News) Electrical engineers at The University of Texas at Arlington and at the University of Wisconsin-Madison have devised a new laser for on-chip optical connections that could give ...

Researchers from Institute for Quantum Computing (IQC), University of Waterloo have demonstrated a new planar chiral mirror that exhibits near unity reflectivity contrast for the opposite spin states ...

Proposals using large light sails like the Starshot Breakthrough, require mirrors with lateral sizes of 4 × 4 m2, thicknesses of 0.05 lambda, reflectivities of 90 %, ppm level optical absorption and a ...
