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.
