Optically active 2D materials could transform areas such as quantum information processing and multispectral imaging.HANK HOGAN, CONTRIBUTING EDITOR, [email protected]Only a few atomic layers thick, 2D materials such as graphene, the compound semiconductor germanium selenium, the transition metal dichalcogenide molybdenum ditelluride, and others could provide new photonic capabilities — better multispectral imaging and single-photon sources, for example. As a result, areas ranging from imaging to quantum information processing could benefit. Graphene is the focus of much research and development, but it’s only one out of as many as a thousand stable 2D materials. That number is far greater when considering possible combinations. ...Read full articleRelated content from Photonics MediaARTICLESResearchers Confirm Strong Magneto-Optical Resonance in GrapheneThe interaction between graphene and light suggests that graphene could be used to control infrared (IR) and terahertz (THz) waves.

This is true for charge-coupled devices (CCDs) and thermal cameras used in machine vision applications where an object's shape, location and orientation vary. Often the culprit is the detector array.If we were to estimate the output of a CCD or thermal camera, we would typically draw an image over the detectors, aligning the image with the detector axes. We show it this way because it’s...Photonics HandbookPositioning System Performance: Understanding the Rules: To make the right decisions and to ensure satisfactory performance in a positioning system, it is necessary to first have a grasp of performance parameters and an understanding of their definitions.Abbe Error — Linear off-axis errors introduced by angular deviations coupled to a moment arm at the point of interest on stage mounted devices (θ in Figure 1).
