Freeform Surfaces Present Opportunities and Challenges The classic example of a freeform surface in ophthalmic applications is the varifocal lens commonly used in eyeglasses. Due to the normal aging process, the eye’s ability to adapt between near and...
Structured Photons Open Door to High-Dimensional Quantum Gates Quantum communication offers unparalleled security and is arguably the most advanced application of quantum information science. Its fundamental strength derives from the fact that single photons can...
Ultrafast Lasers Probe the Fingerprint Region Twenty years ago, spectroscopists typically relied on a toolbox of analytical techniques to collect the data needed to make measurements. From gas chromatography and mass spectrometry to...
Earth Imaging Reveals the True State of Land, Sea, and Air Stephen Hawking once said, “Remember to look up at the stars and not down at your feet.” This deep-seated urge to make sense of where we came from and to try to understand what makes the...
Editorial
What swans and turkeys teach us about photonics November tends to remind me of “black swan” events. I blame Nassim Taleb, who coined the term in his eponymous 2007 book. For anyone who somehow managed to navigate the past 13 years — much less the past four — without ever encountering the phrase, a black swan has become commonly defined as an event that lies beyond our normal experience. I find this definition is a bit...
Photonic Fundamentals
Terahertz-Thickness Measurement Applies Itself to Paint and Coatings There is a constant struggle in the transportation industry to balance paint and coating requirements against manufacturing costs and fuel economy. If the paint or coating is too thin, then flaking and peeling may occur. Conversely, if the paint is too thick, it contributes unnecessary manufacturing costs and increases vehicle weight, which can detract from fuel economy. These factors have made...

Girl with a photonic pearl earring In fine art, the “conversation of contrasts” between the use of light and dark is called chiaroscuro. The technique was a signature style of Dutch painter Johannes Vermeer’s. It creates a dramatic depth that was achieved by researchers from the U.S. National Institute of Standards and Technology (NIST) and Nanjing University in China — in a 1- × 1-mm square...
