A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and ...

Researchers have developed a holographic data storage approach that stores and retrieves information in three dimensions by ...

Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...

There is a growing demand for miniaturized optical packages in the space and semiconductor industries. To meet this growing ...

Those who have experienced method development for laser diffraction understand the scenario well: you are dealing with a new type of sample, uncertain about handling a particular detail, and the one ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only limited control of light waves. Metasurfaces, in contrast, are flat and ...

Researchers from Aalto University in Finland demonstrated a proof-of-concept of laser-processed glass to be used as a type of solar concentrator for building integrated PV (BIPV) applications. The ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Most space missions rely on chemical rockets for propulsion. Rockets must carry fuel, which increases spacecraft mass and limits their speed and travel distance. For decades, researchers have explored ...
