This special issue of OPN highlights the most exciting peer-reviewed optics research to have emerged over the past 12 months.
The diffusion of light allows biologists to study tissue at various depths below the surface of a person’s skin. One novel development is the construction of a biological laser from a single cell.
A key component in any optical system is the detector that is used to transform light into a measurement.
Microstructured optical fibers constitute a versatile platform for developing novel optofluidic, sensing and actuating devices—bringing together photonics and microfluidics.
Spectral imaging is particularly important in the biosciences. Raman scattering provides unique spectral signatures that can be used in the study of cell chemistry.
A key optical tool for metrology allows us to use a ruler calibrated in wavelengths of light.
Nonlinear optics allows us to generate sources in new spectral regions and to provide increased signal propagation capability.
We have learned how to construct ordered index-of-refraction-modulated structures that allow us to control the propagation of light. Initially, researchers were simply interested in fabrication; now they are exploring limitations in the structures.
Surface plasmons have the unique capacity to confine light to very small dimensions, but the losses that occur when they propagate have limited their utility.
Exciting work is being done in quantum information theory and the detection of low light levels.
The atmosphere is nearly opaque at wavelengths from the far-infrared to the millimeter wave, but there are applications that work around this restriction.
A new design concept for optical devices comes from the mathematical view of space-time in general relativity. The desired optical path is determined by coordinate transformations.
Techniques that use optical pulses extending from the picosecond to the attosecond have become an important adjunct to nanoscale science.
The display of 3-D objects has always been fascinating. Recent research explores new possibilities in holographic imaging and 3-D television.
Scientists describe how unusually high photo-induced voltages are generated in thin films of bismuth ferrite.
Coded-aperture spectrometers have enabled high-speed applications that
were once considered impractical with traditional slit devices. This article
traces the history of this type of spectroscopy, from the earliest analog
forms to the latest technology.
Unlike the telephone, the television did not have one clear inventor. It was shaped
over decades by the minds of researchers as well as science fiction writers. When
it was first conceived and developed, a device that could instantaneously transmit
images was referred to as a “telephote.”
A member of the University of Arizona College of Optical Sciences student chapter recently conducted an outreach program to initiate learning and collaborative relationships with scientists, engineers and high school students in Chile.
John Adolph Sanderson, OSA’s president in 1967, is remembered for his work on infrared radiation with the U.S. military, his dedication to improving optics education and his great contributions to the Society.
An advance in superresolution imaging will give scientists the ability to observe how proteins and other molecules interact in living cells in near real time.
A new holographic microscope is inexpensive, compact and lightweight, and can be used for both transmission and reflection imaging with resolutions down to 2 µm.
A team based at the University of California, Berkeley,has liberated surface plasmon polaritons from the confines of fixed guiding nanostructures.
