Optics Summaries
This special issue of Optics & Photonics News (OPN) highlights the most exciting research to emerge in the preceding 12 months in the fast-paced world of optics.
Nanophotonics
Researchers have developed techniques for using light to probe sub-wavelength dimensions.
Optical Engineering
Supercontinuum fiber laser technology is at a stage where compact, high-power white-light sources are commercially available at a low cost.
Phase Sensing
Phase sensing has led to advances in X-ray beam characterization and cellular microsurgery.
Photonic Systems
Applications of photonic structures continue to expand not only into the optical equivalents of semiconductor properties but into quantum optics.
Plasmons and Surface Waves
Recent work is focusing on plasmons that propagate at the metal/air interface.
Quantum Computing
Researchers have developed quantum memory that is multi-mode and well-adapted for time-bin qubits.
Raman Spectroscopy
Coherent anti-Stokes Raman techniques are increasing the utility of Raman scattering for chemical and biological diagnostics.
Slow Light
Images imprinted on a laser pulse can be dramatically slowed when traversing an alkali vapor medium via electromagnetically induced transparency.
Solar Power
Organic photovoltaics is an active research area because thin-film solar cells can be processed directly onto large-area substrates and patterned into modules, thus lowering manufacturing costs.
Statistical Optics
Working at the noise level of an optical signal, we can engineer unexpected performance.
Terahertz Technology
We regularly return to the wavelength region between 30 µm and 1 mm to exploit this underdeveloped spectral range.
Transformational Optics
Transformational optics is no longer just about cloaking. True to its name, it is transforming the entire field of physical optics.
Ultrafast Optics
The space-time duality of electromagnetic waves allows for the creation of temporal waveforms and the measurement of their properties.
Propagation
Simple diffraction does not establish the limits on lateral resolution. We can use our new knowledge of light propagation to develop ultrasensitive instruments.
X-Ray Lasers
Researchers have achieved a 1-ps pulse from a compact soft X-ray laser plasma amplifier.
Departments and Columns
JP Mfg. Inc.: Keeping Optics in the Family
A manufacturer of plastic injection-molded optics has been a successful family affair for 40 years. It is also helping the town of Southbridge, Mass., U.S.A., to carry on an optics heritage that dates back to the 19th century, when New England workers founded the American Optical Company.
High-Tech Workers Part of U.S. Immigration Debate
If Congress takes up immigration legislation before the end of next year—which President Obama and congressional leaders have vowed to do—lawmakers will consider competing proposals for changing the way U.S. employers hire workers from overseas.
Adaptive Optics for Better Vision Correction
Optical scientists at the University of Murcia (Spain) bring the measurement of eyesight correction into the 21st century with adaptive optics.
Presidents of the 1920s
A look at four early Society leaders.
Diamond Raman Lasers Gain Efficiency
Two Australian scientists have created a diamond Raman laser with a conversion efficiency of 63.5 percent—the best yet.
