How Vision Systems Can Deliver More than the Sum of Their Parts The use of both 3D-imaging technology and smart cameras is expanding the flexibility and capabilities of machine vision systems. Integrating these elements with advanced image preprocessing and...
Optical Frequency Combs Enhance Hyperspectral Imaging An optical frequency comb is an optical source characterized by a spectrum consisting of evenly spaced frequency lines, known as teeth. This Nobel Prize-winning technology has become a reference tool...
Editorial
Light finds a way Uncertainty is part of life in any year. But the uncertainties arising from 2020’s global pandemic have literally remapped daily life. In a climate of such ambiguity, our brains tend to seek patterns or milestones — a tendency I was reminded of recently as I began mapping out the first Photonics Spectra issues of 2021. The planning process forced me, for the first time in over half a year, to...

New One-step Fabrication Technique Yields Ultrathin Flat Lenses An international team of researchers has developed a method of fabricating high-performance lenses in monolayer two-dimensional transitional metal dichalcogenide (TMDC) material using a femtosecond laser. The lens has a subwavelength resolution and a focusing efficiency of 31%, which marks a step closer to ultimately thin optical devices for use in nano-optics and on-chip photonic applications....
Cost-Effective Coatings for Smart Windows Rival Industry-Standard Performance An inexpensive, ultrathin spray-on window coating for blocking heat and conducting electricity could further reduce energy costs for smart windows and heat-repelling glass, making smart window...

Metasurface Added to Photonic Chip to Improve Footprint, Control A team of researchers at Penn State has integrated metasurfaces onto a photonic integrated circuit (PIC) chip. The design maintains high light controllability, allowing guided waves inside the PIC to...
Researchers Turn Laser Sintering on Its Head Selective laser sintering (SLS), a process that uses a laser to heat powder materials to the point where the micron-scale particles fuse together to form a solid mass, is one of the most widely used...
Photonic Crystal Generates VUV Light at Wavelengths Suitable for Spectroscopy Researchers at the University of Tokyo have created a tabletop device that efficiently generates circularly polarized vacuum ultraviolet (VUV) light using an ultrathin film with nanoscale...
Silicon CCD Camera Peers into Mid-Infrared Researchers at the University of California, Irvine used the nonlinear optical properties of the silicon (Si) chip in a Si-based camera to enable a mid-infrared (MIR)-specific response in the camera....
Strain Engineering of 2D Materials Enables More Effortless Photodetection Using a 2D material and an approach it calls “strainoptronics,” a George Washington University research team created a photodetector that can operate with high efficiency at the...
Photonic Processing Unit Supports Light-Speed Machine Learning Substituting a photonic tensor core for existing digital processors such as GPUs, a pair of engineers from George Washington University (GWU) has introduced a new technique for performing high-level...

Mechanochromic, thermochromic, piezochromic … or just pretty It took nature millions of years to develop the tiny scales that give butterfly wings — which are themselves transparent — their intense coloration. Like peacock feathers, they derive their signature hues from structures rather than pigments. Now, a team led by scientists at the University of Surrey and the University of Sussex in England has borrowed from nature’s bag of tricks to...
