Optics Express Focus Issue: Breakthroughs in Unconventional Polarization States of Light

WASHINGTON, May 10 - It has been known for many years that careful control of the polarization of light can impact optics and photonics technologies. For example, tiny nanostructures are known to be able to capture light from a region much larger than their size if the polarization of the laser illumination is designed correctly. Dark spots in a beam known as optical vortices can produce new and intriguing effects when used along with polarization control in a microscope. To highlight breakthroughs in this area, the editors of Optics Express, the Optical Society's (OSA) open-access journal, today published a special focus issue on Unconventional Polarization States of Light. The issue was organized and edited by Thomas G. Brown of the Institute of Optics at the University of Rochester and Qiwen Zhan of the University of Dayton.

"What once was a side curiosity of optics is now joining the mainstream, both in fundamental investigations and in applications," said Brown. "Research in this focus issue will cover polarization breakthroughs that have the potential to affect a broad range of disciplines - from nanomaterials to laser devices."

Summary

The polarization of light can play an important role in optical trapping, interaction with nanostructures, and focusing in microscopy. The seminal work in the mid-1990s by Colin Sheppard, now at the National University of Singapore, and Dennis G. Hall now at Vanderbilt University launched a flurry of studies in the last decade on the creation and focusing of polarized beams that have certain geometrical symmetries. Beams with a spoke-like "radial" polarization were of particular interest because of their potential for creating small focal regions of axially polarized light, a key requirement for interacting with nanostructures and coupling to fields tightly confined to metal surfaces. For unconventional polarization states of light, the geometrical arrangement of the polarization can produce vortex behavior in beam propagation, a result that has intrigued physicists and changed how optical engineers think about illumination in microscopes and lithography systems. Meanwhile, the creation of unconventional polarization states within compact laser cavities has offered new ways to begin incorporating these states into more complex optical systems.

Key Findings & Selected Papers

The following papers are some of the highlights of the Optics Express focus issue on Unconventional Polarization States of Light. All are included in volume 18, issue 10 and can be accessed online at http://www.OpticsInfoBase.org/OE.

 

  • A paper from the Max Planck Institute describing the use of unconventional polarization states to probe the scattering properties of a single nanostructure, a result that will be of tremendous help in understanding more complex arrays, which have potential uses in metamaterials research. "On the experimental investigation of the electric and magnetic response of a single nanostructure" Peter Banzer, Ulf Peschel, Susanne Quabis, and Gerd Leuchs, Max Planck Institute for the Science of Light. pp. 10905-10923.

New Technique Accurately Digitizes Transparent Objects

A new imaging technique makes it possible to precisely digitize clear objects and their surroundings, an achievement that has eluded current state-of-the-art 3D rendering methods. The ability to create detailed, 3D digital versions of real-world objects and scenes can be useful for movie production, creating virtual reality experiences, improving design or quality assurance in the production of clear products and even for preserving rare or culturally significant objects.

Core Solutions Reach Optimally Extreme Light Pulses

As scientist probe nature ever more precisely with laser pulses, now aiming for the zeptosecond regime – a trillionth of a billionth of a second and the fastest scale of time measured – optimizing each parameter of those pulses can offer more finely tuned measurements of as-yet unknown dynamic properties. The laser wavelength, duration and energy of each pulse, and rate at which pulses are produced are all key factors in observing dynamics such as the real-time electron motions of single molecules together with the motion of consistituent atoms.

Clamping Down on Causality by Probing Laser Cavities

Since the realization of the first laser cavity countless questions have been asked for which laser light has provided the answer. Numerous questions have also been posed in an effort to improve on our abilities to produce lasers with various performance specifications and wavelengths. A question that was not asked until recently is – what happens if you shine a laser beam through another laser cavity? It may not seem a practical question to ask experimentally, but after studying how externally incident light interacts with an active laser cavity in quantitative detail, the answer turns out to offer devices with new, seemingly paradoxical optical capabilities.
