Optical Fiber Used to Direct, Stabilize Random Laser
ALBUQUERQUE, N.M., Oct. 30, 2017 — An advance in laser technology combines the broad spectral features of a random laser with the spectral stability and high directionality of a traditional laser. Such an advance could enable greater use of random lasers in applications where a broad spectrum illumination source would be of benefit. Researchers at the University of New Mexico, in collaboration with researchers at Clemson University and the University of California San Diego, demonstrated a directional random laser in a

Label-Free Imaging Maps Brain Changes in Alzheimer's Mouse Model
WUHAN, China, Oct. 20, 2017 — An imaging system called cryo-micro-optical sectioning tomography (cryo-MOST) could help speed new drug development for Alzheimer’s disease by offering a better way to monitor the brain changes indicative of Alzheimer's in mouse models....
Broad Palette of Fluorescent Dyes May Advance Biological Imaging
ASHBURN, Va., Oct. 19, 2017 — To better illuminate the inner workings of cells, researchers have developed a way to adjust the properties of fluorescent dyes deliberately, resulting in an expanded palette of dyes that are bolder, brighter and more cell-permeable. Their novel...
Indiana University Wins Grant to Advance Medical Nanotechnology
BLOOMINGTON, Ind., Oct. 18, 2017 — One year after establishing the intelligent systems engineering program in the Indiana University (IU) School of Informatics, Computing and Engineering, the university has been awarded a five-year, $4 million grant from the National Science...
Optical Systems Capture First Light From Colliding Neutron Stars
LIVINGSTON, La., HANFORD, Wash. and CASCINA, Italy, Oct. 17, 2017 — Scientists from the international LIGO and Virgo Scientific Collaborations have announced the detection of the bright spark of two neutron stars colliding. This event has been dubbed GW170817 because it sent ripples through space-time that reached...
Photodetector Uses Ultrathin Materials to Increase Efficiency
RIVERSIDE, Calif., Oct. 17, 2017 — A prototype developed using quantum mechanical processes could usher in a novel class of ultra-efficient photodetectors that would enable solar cells to turn the light they receive into multiple electrons. The prototype is based on the efficient...
The Optical Society Announces 2018 Fellows Class
WASHINGTON, Oct. 16, 2017 — One hundred and one (101) OSA members, representing 19 countries, have been elected to the 2018 OSA Fellows Class. Fellows are selected based on specific scientific, engineering, and technological contributions, technical or industry leadership in...
Single Photon Reveals Quantum Entanglement of 16 Million Atoms
GENEVA, Oct. 16, 2017 — Scientists have demonstrated entanglement between 16 million atoms in a crystal crossed by a single photon, reinforcing the quantum theory that entanglement can persist in macroscopic physical systems. The theoretical study of large-scale...
Camera Design Mimics Sophisticated Visual System
CHAMPAIGN, Ill., Oct. 16, 2017 — The bio-inspired design of an ultra-sensitive camera that is capable of sensing both color and polarization is based on the visual system of the mantis shrimp. The camera features a single-chip, low-power, high-resolution color-polarization imaging...
