| Material Absorbs Nearly 100% of IR Light |
 |
An ultrathin, tunable device developed at Harvard absorbs 99.75% of infrared light on demand and, when activated, looks like a black blob to IR cameras. The near-perfect absorber could expand the possibilities for energy harvesting and thermal detection. “We exploit a kind of naturally disordered metamaterial, along with thin-film interference effects, to achieve one of the highest absorption rates we’ve ever seen. Yet our perfect absorber is structurally simpler than anything tried before, which is important for many device applications,” said principal investigator Federico Capasso. |

| Metamaterials Manipulate Light on a Microchip |
| Controlling light on a microchip is no easy feat, but new theoretical designs for miniaturized optical devices made of metamaterials devised at Pennsylvania State University may be the solution for manipulating light on integrated circuits. |

| Raman Researchers Set a Trap to Cool Ions |
| Captured ions can be cooled, rather than heated, through contact with cold atoms, and these ion traps can store them in a stable condition for longer periods than previously demonstrated. The unexpected results could pave the way to experiments that generate molecular ions at interstellar space temperatures. |

| Tiny Probes Dramatically Boost Raman Signals |
| Novel gold nanoparticles can goose the signal from Raman reporters, or molecules whose jiggling atoms respond to a probe laser by scattering light at characteristic wavelengths. The discovery could lead to better-targeted drug delivery and deeper bioimaging within tissue. |

In this week’s edition of the industry’s premier weekly newscast: a tunable new device absorbs nearly 100 percent of the infrared light that hits it, biomarker binding Brights boost Raman signals, an antenna on a chip works in 3-D free space, nanocrystals convert sunlight to solar steam, and some notable acquisition news from Oclaro and Thorlabs. Hosted by Photonics Media’s Laura Marshall and Melinda Rose. |

| ‘Hyper’ Ramsey Excitation Confirmed |
| Shining laser light onto atoms and molecules is the best way to obtain precise information about their inner structure, but light above a certain intensity can fundamentally change their energy levels. A group in Germany has demonstrated how to prevent such “light shifts,” and their method could make optical atomic clocks even more accurate. |

| Antenna on a Chip Zips Through 3-D ‘Free Space’ |
| A new micron-scale spatial light modulator (SLM) works in 3-D “free space” and runs orders of magnitude faster than those used in sensing and imaging devices, and it holds great potential for imaging, display, holographic, measurement and remote sensing applications. |

|
| Photonic Nanocrystals Convert Sunlight to Solar Steam |
| Light-capturing nanoparticles so efficient at turning sunlight into heat have been shown to produce solar steam from nearly frozen water. Inventors of the new technology expect its first uses to be for sanitation and water purification in developing countries rather than for electricity generation. |

| 1st International Biophotonics Meeting in Israel - December 9 – 11, 2012 · Tel Aviv, Israel |
 |
Supported by SPIE, the 1st International Biophotonics meeting in Israel (BPI2012) will gather globally renowned scientists from around the world, Israeli scientists and clinicians, as well as industrialists and entrepreneurs. This group will present their work and discuss open issues in the field, while exposing the up-to-date research at the frontier to local students, researchers, and industrial research and development representatives. The meeting aims to strengthen connections and trigger bi-national and multi-national research collaborations. Keynote speaker will be Steven L. Jacques (Oregon Health & Science University, Depts. of Biomedical Engineering & Dermatology). Conference invited speakers include Irving Bigio, Boston University; Daniel Palanker, Stanford University and Gabriel Idan, Given Imaging.
