Latest Optics Express Stories
New Work in OSA's Journal Optics Express Suggests That Fur Coats and Down Feathers Might Derive Much of Their Impressive Insulating Power from an Unexpected Optical Mechanism Washington,
Engineers at Stanford have developed a prototype single-fiber endoscope that improves the resolution of these much-sought-after instruments fourfold over existing designs.
The nighttime twinkling of fireflies has inspired scientists to modify a light-emitting diode (LED) so it is more than one and a half times as efficient as the original.
The storage of light-encoded messages on film and compact disks and as holograms is ubiquitous---grocery scanners, Netflix disks, credit-card images are just a few examples.
In a new approach to invisibility cloaking, a team of French researchers has proposed isolating or cloaking objects from sources of heat—essentially "thermal cloaking."
Ultrafast lasers, lasers that emit light pulses that are as short as a few femtoseconds, have enabled a wide-range of fundamental science and applications over the past two decades.
If there is life on other planets, a laser frequency comb developed at the National Institute of Standards and Technology (NIST) may help find it.
Existing coherent ultraviolet light sources are power hungry, bulky and expensive. Researchers have found a better way to build compact ultraviolet sources with low power consumption that could improve information storage, microscopy and chemical analysis.
The search for innovative, cost-effective and energy-efficient solutions for display and lighting applications are the focus of ongoing intense worldwide photonics research and development activities.
