The orbital angular momentum (OAM) of electromagnetic waves — a kind of “structured light” — is associated with a helical or twisted wavefront. The helical modes are characterized by a topological ...

Light propagation is usually reciprocal meaning that the trajectory of light travelling in one direction is identical from that in the opposite direction. Breaking reciprocity can make light propagate ...

A team of researchers at Penn State have devised a new, streamlined approach to designing metasurfaces, a class of engineered ...

(Nanowerk News) Metasurfaces are artificial array structures consisting of subwavelength unit cells arranged on a specific two-dimensional surface. Dynamic, reconfigurable metasurfaces are an ...

Penn State researchers use large language models to streamline metasurface design, significantly reducing the time and ...

Metalenz metasurfaces are now on the market through its partnership with STMicroelectronics, marking the introduction of this revolutionary optical technology in real-world devices Metalenz’s ...

A project at Pennsylvania State University (Penn State) has developed a metasurface intended to extract polarimetric imaging data more rapidly and cost effectively than current methods. Described in ...

A time-of-flight sensor from STMicroelectronics marks the commercial introduction of Metalenz metasurface technology. The metasurface component within the VL53L8 direct time-of-flight (dToF) sensor is ...
