The article offers information on the chirped-mirror design developed by scientists in the Krausz group at Ludwig-Maximilians in Garching, Germany. Their innovation has a high-enough group-delay dispersion, used for purposes traditionally reserved for prisms or gratings including chirped-pulse amplifiers (CPA) or high-energy femtosecond-laser chirped-pulse oscillators (CPO).

The article reports on the application of hyperacuity by the researchers from Fraunhofer Institute for Applied Optics and Precision Engineering (IOF) and Friedrich Schiller University Jena in Germany. Hyperacuity is the natural phenomenon of seeing images with an accuracy exceeding that of the vision system's capabilities. The purpose of which is to gain access to highly accurate information beyond the resolution limit of an artificial compound eye.

The article provides information on the low-loss terahertz waveguide developed by researchers at Rheinisch-Westfälische Technische in Aachen, Germany out of their investigation on the two parallel rectangular dielectric slabs for the terahertz waveguide. An overview of the investigation made by the researchers about the advantages of split rectangular waveguides (SRW) integrated circuit is offered. The result shows the potential of SRW for terahertz optics.

The article describes enhancements to single-frequency laser systems made by scientists at Laser Zentrum Hannover and its spin-off company InnoLight in Germany. Their results led to the development of Nd:YAG laser systems used for the detection of gravitational waves and high-precision optical frequency standards.

Focuses on the existence of a black hole in the Milky Way according to astronomers in Garching, Germany. Observation of normal star orbiting the supermassive black hole at the center of the galaxy; Description of the images taken of the black hole using a Nasmyth adaptive optics system; Emission of energy by black holes from galaxies and quasars.

The article reports on the development of researchers on isotopic stimulated-emission-depletion (isoSTED) microscopy system that uses optical path to simplify the microscope's optical design in Germany. It notes that the focal-point size in STED microscopy is reduced resulting in improved imaging solution. It states that researchers devised a modified STED microscope to eliminate one beam path and align the optical design. Moreover, STED setup was able to resolve individual microtubules.

The article reports that researchers at the University of Stuttgart in Germany recently created a stacked splitring metamaterial for the optical wavelength range. This breakthrough may eventually lead to and reach beyond Duke University's work. Harald Giessen's research group at the University of Stuttgart designed and manufactured a three-dimensional optical infrared metamaterial with a fabrication process that involves planarization, lateral alignment and a layer-by-layer stacking approach.
