Conquering the Silicon Photonics Production Bottleneck The first computer link using optical fibers was commissioned four decades ago to safeguard communications at the Cheyenne Mountain strategic command center1. We have since seen broad adoption of photonic communications in an unfolding trend of diminishing scale. Transoceanic fiber cables have replaced satellite links; photonic communications have become the backbone of transcontinental...
Flat Surface Lens Overcomes Limitations of Conventional Optics The telescope has been used for more than 400 years. Although there have been many designs created for looking at distant objects, there is a fundamental weakness with the lens system. By necessity,...
Smart Perception is the Next Stage for Machine Vision Intelligent robotics is one of the technological disruptions that will fundamentally alter society — both from an industrial and a social perspective. And “smart perception” is a...
Portable Spectroscopy and the Fight Against Food Fraud Food fraud and adulteration is a serious and increasing problem with significant health and economic impacts. Although robust and sophisticated laboratory methods have been developed to detect fraud,...

Editorial
The Fight Against Food Fraud Cases of food fraud — some of which cause serious illness and death — are a global issue. Forty-seven people died in 2012 in the Czech Republic after drinking spirits spiked with methanol. Tens of thousands of infants were hospitalized and six died in China after it was discovered that melamine had been added to baby formula to boost its protein content. Sophisticated laboratory...

NASA Investigates Optical Coatings for Far-UV Spectral Range To meet the projected goals for its next generation of space telescopes, NASA is taking on a new optical challenge — the fabrication of protective coatings for mirrors to be used for astrophysics studies in the Lyman Alpha range. So far, no one has developed a coating that effectively protects and maintains an aluminum mirror’s high reflectivity in the 90- to 130-nm range, also known...
Graphene-CMOS High-Res Sensor Images Visible and IR Light at the Same Time Graphene instead of silicon has been used for a CMOS integrated circuit, resulting in a high-resolution image sensor consisting of hundreds of thousands of photodetectors based on graphene and...
Jellyfish Proteins Used to Create Unconventional Laser A polariton laser based on lab-grown, fluorescent jellyfish proteins could impact the fabrication of artificial optical devices, advance the field of optical computing — as it require less...
Quantum Effect Changes Direction of Light Waves In a variation of the magneto-optical effect, special materials called “topological insulators” (TI) demonstrated the ability to switch the direction of a light wave in clearly defined...
Persistent Photoconductivity Used to Control Semiconductor Cells Use of light to alter the conductivity of semiconductor material could provide a new way to control cell behavior on semiconductors used for bioelectronics. The approach draws on persistent...
Unpolarized Single Photons Generated With True Randomness The generation of single photons in random polarization states from diamond could have significance in the development of quantum cryptography and the testing of fundamental problems in quantum...
Perovskite Stability Could be Improved by Atomic-Scale Redesign The mechanism that causes solar cells made with organic lead halide perovskites to rapidly deteriorate when exposed to oxygen and light has been discovered, and could provide the basis for solving...
Laser Pulses, Class of New Materials Show Potential for Energy Efficiency An experiment that involves the cutting edge of condensed matter physics and materials science could make superconductivity at room temperature and more efficient energy usage a reality. An...
Photodielectric Discovery Could Mean Greater Optical Control for Electronics The instrinsic photo-dielectric effect (PDE), which uses light to increase the permittivity of the dielectric used in capacitors, could aid in the development of photo-capacitors that would enable...
