Optical Coatings Take a Leap Forward
A novel crystalline coating technique that produces low-loss mirrors could help accelerate progress in the development of lasers for precision measurement applications. The work, a collaboration between the University of Vienna and JILA, a joint institute of the University of Colorado at Boulder and NIST, builds on advancements in semiconductor lasers, quantum optomechanics and microfabrication to demonstrate low-loss mirrors based on substrate-transferred epitaxial multilayers that exhibit both unprecedentedly low mechanical loss and high optical quality. The creation of such high-quality optical coatings could have a significant impact on the performance of narrow-linewidth lasers used in precision sensing applications.

3-D Display Doesn't Disturb 2-D Viewers
Watching 3-D TV with stereo glasses can be cumbersome, and taking them off to give your eyes a break only leaves you staring at a blurry image. But a 3D+2D display could change that, enabling viewers with glasses to see images in 3-D, while those without them see clear images in standard 2-D.

Photodetector Discerns Polarized Light Intrinsically
Few photodetector materials can discern polarized light — individual electromagnetic waves oscillating parallel to one another — directly without the use of a grate or a filter. For a newly created carbon-based broadband photodetector, however, polarimetry is intrinsic to the active material.

SPIE Optics + Photonics is the largest interdisciplinary technical conference in North America, presenting the latest research and technologies in solar, nano, optics, photonics and space optics. The conference’s four symposia (Nanoscience + Engineering, Solar Energy + Technology, Organic Photonics + Electronics, and Optical Engineering + Applications) will offer more than 3200 presentations, including plenary and featured talks on topics such as metamaterials for molded optical wavefronts, asteroid-tracking and collision-mitigation, Kepler’s search for Earthlike planets and nanoparticle technology to convert solar energy directly into saturated steam for sterilizing tools and waste. The show also will include more than 40 professional development courses, poster sessions, panel discussions and a tribute to H. John Caulfield.
