Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.

Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...

U.H.P. Fischer earneda degree in physics from the Free University of Berlin, Germany in1983. In 1988 he made his PhD in physics of condensed matter. In1988 he joined the Heinrich-Hertz-Institute in ...

As modern communication and sensing systems demand ever higher speeds and efficiencies, integrated photonics has emerged as a critical enabling technology. Thin-film lithium niobate (TFLN), known for ...

These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...
