Cover Story

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. more>>



Researchers have developed techniques for using light to probe sub-wavelength dimensions. more>>

Optical Engineering

Supercontinuum fiber laser technology is at a stage where compact, high-power white-light sources are commercially available at a low cost. more>>

Phase Sensing

Phase sensing has led to advances in X-ray beam characterization and cellular microsurgery. more>>

Photonic Systems

Applications of photonic structures continue to expand not only into the optical equivalents of semiconductor properties but into quantum optics. more>>

Plasmons and Surface Waves

Recent work is focusing on plasmons that propagate at the metal/air interface. more>>

Quantum Computing

Researchers have developed quantum memory that is multi-mode and well-adapted for time-bin qubits. more>>

Raman Spectroscopy

Coherent anti-Stokes Raman techniques are increasing the utility of Raman scattering for chemical and biological diagnostics. more>>

Slow Light

Images imprinted on a laser pulse can be dramatically slowed when traversing an alkali vapor medium via electromagnetically induced transparency. more>>

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. more>>

Statistical Optics

Working at the noise level of an optical signal, we can engineer unexpected performance. more>>

Terahertz Technology

We regularly return to the wavelength region between 30 µm and 1 mm to exploit this underdeveloped spectral range. more>>

Transformational Optics

Transformational optics is no longer just about cloaking. True to its name, it is transforming the entire field of physical optics. more>>

Ultrafast Optics

The space-time duality of electromagnetic waves allows for the creation of temporal waveforms and the measurement of their properties. more>>


Simple diffraction does not establish the limits on lateral resolution. We can use our new knowledge of light propagation to develop ultrasensitive instruments. more>>

X-Ray Lasers

Researchers have achieved a 1-ps pulse from a compact soft X-ray laser plasma amplifier. more>>
