Novel Material May Allow Everyday 3D Holography
MELBOURNE, Australia, June 15, 2017 — What could be the world’s thinnest hologram could also be the harbinger of what’s to come in consumer electronics, by paving the way for 3D holography compact enough to be integrated into everyday electronics like smartphones, laptops and TVs. Developing holograms that are thin enough to work with electronics has challenged scientists. Holography currently has extensive applications in optical microscopy and imaging, 3D displays and metrology; but to integrate holography with
Laser-Induced Graphene Inhibits Biofouling, Kills Bacteria
HOUSTON, June 14, 2017 — Laser-induced graphene (LIG) has been shown to be effective in resisting biofouling (the buildup of biological material on wet surfaces) and, when used as electrodes with a small applied voltage, in destroying bacteria. “This form of graphene...
Optical Approach Delivers Fast, Scalable Data Transmission
KARLSRUHE, Germany, June 14, 2017 — Microresonator soliton frequency combs have been shown to considerably increase the performance of wavelength division multiplexing (WDM) techniques in optical communications. The technology could be used to develop efficient, highly scalable...
Low-Cost Synthetic Material Produces White Light That Imitates Sunlight
TURKU, Finland, June 13, 2017 — Persistent luminescence materials are used in everyday glow-in-the-dark applications and show high potential for medical imaging, night-vision surveillance, and enhancement of solar cells. The materials that make these applications possible contain...
Underwater Touchpad Will Open Window Further Into the Dolphin Mind

Clemson Receives Funding from DoD for Laser Weaponry Research
CLEMSON, S.C., June 13, 2017 — Two researchers at Clemson University are taking different but complementary approaches to creating a high-energy laser that could be used as a weapon. The engineers are receiving a combined $3.2 million from the Department of Defense to help fund...
Hybrid Imaging Method Delivers Panoramic Scan of a Live Animal
DURHAM, N.C., June 12, 2017 — A hybrid imaging technique, dubbed Single-Impulse Panoramic Photoacoustic Computed Tomography (SIP-PACT), combines light and ultrasound to provide a full cross-sectional view of a small animal’s internal functions in real time, with enough...
Photons and Electrons Produce Hybrid Light-Matter Fluid
MONTREAL, June 9, 2017 — Light is composed of waves, but it can also behave like a liquid. In certain circumstances it can ripple and spiral around obstacles. These liquid properties of light emerge when the photons that form the light wave interact with each other....
Imaging Technique Could Improve Tumor Margin Assessment
LONDON, June 7, 2017 — Use of Cerenkov luminescence imaging (CLI) could provide a more accurate technique for assessing resection margins during breast-conserving surgery, a primary treatment for early-stage breast cancer. CLI combines optical and molecular imaging by...
Quantum Emitters Generate Single Photons on Demand
CAMBRIDGE, England, June 6, 2017 — Quantum light emitters have been observed previously in atomically thin layers of transition metal dichalcogenides (TMDs). However, they have been found at random locations within the host material and usually in low densities, hindering experiments...
3D-Printed Patch Mends Hearts
MINNEAPOLIS, June 6, 2017 — A new 3D laser printed patch has been developed that can help heal scarred heart tissue after a heart attack. Researchers from the University of Minnesota-Twin Cities, University of Wisconsin-Madison, and University of Alabama-Birmingham used laser...
Nominate an Outstanding Educator for an Industry Beacon Award
PITTSFIELD, Mass., June 5, 2017 — Each year, Photonics Media honors a few standout contributors to the photonics and optics industry who have made a difference through their efforts and achievements in photonics science, business or education. The Beacons program is fueled by...
Metalens for Immersion Microscope Overcomes Challenges of Hand-Polishing Techniques
CAMBRIDGE, Mass., June 2, 2017 — A flat lens for immersion microscopy has been developed. The lens, which can be designed for use with any form of liquid, could provide a cost-effective and easy-to-manufacture alternative to hand polishing lenses for immersion objectives. Because...
A Marriage Made in Self-Driving Heaven
Jun 2, 2017 — Meet Marilyn and Martti — automated cars developed by the VTT Technical Research Centre of Finland. They’re the first self-driving cars to be granted road traffic testing permits in the country, thanks to a suite of sophisticated optical...
NASA Investigates Optical Coatings for Far-UV Spectral Range
GREENBELT, Md., June 1, 2017 — 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...
Graphene-CMOS High-Res Sensor Images Visible and IR Light at the Same Time
BARCELONA, Spain, May 31, 2017 — 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 quantum dots (QDs). This graphene-QD CMOS sensor can be...
Jellyfish Proteins Used to Create Unconventional Laser
ST. ANDREWS, Scotland, May 31, 2017 — 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 energy than conventional lasers — and aid in new...
Holographic Technique Traps Irregularly Shaped Microscopic Objects
DAEJEON, South Korea, May 26, 2017 — An optical manipulation technique that can securely control the position, orientation and shape of non-spherical microscopic samples, such as living cells, could have direct applications in biophotonics and soft matter physics. Although optical...
Quantum Effect Changes Direction of Light Waves
VIENNA, May 26, 2017 — 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 quantum leaps rather than continually. This...
Persistent Photoconductivity Used to Control Semiconductor Cells
RALEIGH, N.C., May 23, 2017 — 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 photoconductivity, a phenomenon that causes some materials...
Light Exposure in the Evening Improves Sports Performance
BASEL, Switzerland, May 23, 2017 — A new study shows that athletes who are exposed to blue light before competing can significantly improve their end performance. Researchers at the University of Basel’s Department of Sport, Exercise and Health investigated whether light...
