Metasurfaces Control Polarized Light at Will

Researchers at SEAS have uncovered hidden potential in metasurfaces and demonstrated optical devices that manipulate light’s polarization state with an unprecedented degree of control. Read on to learn more.

Terahertz Energy Focused by Credit Card-Sized Device to Generate High-Resolution Images

Researchers have created a device that enables them to electronically steer and focus a beam of terahertz electromagnetic energy with extreme precision. This opens the door to high-resolution, real-time imaging devices that are hundredths the size of other radar systems and more robust than other optical systems.

High-Brightness Source of Coherent Light Spanning from the UV to THz

An international team of researchers reports on a compact high-brightness mid-IR-driven source combining a gas-filled anti-resonant-ring photonic crystal fiber with a novel nonlinear-crystal. The tabletop source provides a seven-octave coherent spectrum from 340 nm–40,000 nm with spectral brightness 2–5 orders of magnitude higher than one of the brightest synchrotron facilities.

Highest-Resolution Single-Photon Superconducting Camera

The NIST camera is made up of grids of ultrathin electrical wires, cooled to near absolute zero, in which current moves with no resistance until a wire is struck by a photon. In these superconducting-nanowire cameras, the energy imparted by even a single photon can be detected because it shuts down the superconductivity at a particular location (pixel) on the grid. Combining all the locations and intensities of all the photons makes up an image.
