Early Melanoma Detection Device Completed
BEVERLY HILLS, Calif., Oct. 20, 2010 — Spectral Molecular Imaging Inc. (SMI) said it recently completed development of its initial product, SkinSpect, aimed at early detection of melanoma through SMI's proprietary form of hyperspectral imaging.
Queen’s University Selects Linkam Stages
TADWORTH, England, Aug. 20, 2010 — For 10 years, Linkam Scientific Instruments has been used as temperature stage suppliers to Queen’s University in Canada to study the properties of ferroelectric liquid crystals. The research program, led by Professor Robert Lemieux and his...
Transformation Optics Makes a U-turn
BERKELEY, Calif., July 7, 2010 — In transformation optics, light waves can be controlled at all lengths of scale through the unique structuring of metamaterials, composites typically made from metals and dielectrics — insulators that become polarized in the presence of an...
Adding Fiber Pays Off for Industry
Jul 1, 2010 — For Electro Scientific Industries Inc. (ESI) of Portland, Ore., getting fiber into its diet has been one key to success. Among other things, the company makes a line of micromachining systems for the semiconductor, flat panel display, photovoltaic...
Spin-Statistics Theorem Survives Test
BERKELEY, Calif., June 28, 2010 — The most rigorous trials yet of a fundamental assumption about how particles behave on the atomic scale has been conducted at the University of California at Berkeley. "We tested one of the major theoretical pillars of quantum field theory,...
Novel Metamaterial Responds to Visible Light
PASADENA, Calif., April 27, 2010 — An artificial optical material with a three-dimensional structure has been engineered to bend light in the “wrong” direction from what normally would be expected, irrespective of the angle of the approaching light. This new type of negative-index...
ARRA to Help Build Telescope
BALTIMORE, March 22, 2010 — A team led by Charles L. Bennett of Johns Hopkins University has won a $5 million National Science Foundation grant – administered through the federal stimulus package – to build a telescope that will probe what happened during the universe’s first...
Tracking Particles With Gold Rods
HOUSTON, Feb. 8, 2010 – A group of Rice University researchers, led by Stephan Link, has found a way to use nanometer-scale gold rods as orientation sensors by combining their plasmonic properties with polarization-imaging techniques. The work may make it possible to see...
Stirring Up a Passion for Photonics
SAN FRANCISCO, Jan. 24, 2010 — It rather stands out among the shiny high-tech devices strung along the aisles at the BiOS trade exhibition — a simple pine valise propped open at one of the tables belonging to Om...
Spintronics Go All-Electric
CINCINNATI, Oct. 28, 2009 – An innovative and novel way to control an electron's spin orientation using purely electrical means has been created for the first time. A multidisciplinary team of University of Cincinnati researchers created the all-electric spin electronics, or...
Quantum Signatures of Chaos
TUCSON, Ariz., Oct. 9, 2009 – No one has produced experimental evidence that chaos occurs in the quantum world – the world of photons, atoms, molecules and their building blocks – until now. In a series of experiments, professor Poul Jessen and a group at the University of...
A New World of Fiber Sensors
Oct 1, 2009 — Optical fiber is well-known for its ability to carry information at high speeds over long distances. Twenty years after the first transatlantic fiber optic cable was laid, these strands of ultrapure glass continue to offer unrivaled bandwidths. They...
Flat Screens Go Deep – and More
Sep 1, 2009 — The Duchess of Windsor was half right, at least as far as displays are concerned: They really never can be too thin, as evidenced by the rise of flat screens of all varieties and of displays that can be virtually anywhere. But as for being too rich,...
An Optical Diode From Nonlinear Light Absorbers
Jul 14, 2009 — An interesting study was taken up by Dr. Reji Philip of the Raman Research Institute, Bangalore, on a novel kind of optical diode, while he was working on a sabbatical in the research group of Prof. D.V.G.L.N. Rao of the physics department,...
A Faster Single-Atom Detector
COLLEGE PARK, Md., May 19, 2009 -- A new single-atom detection system that uses two polarizations of light simultaneously through cavity mirrors is more than 99.7 percent accurate and can discern the arrival of a neutral atom in less than one-millionth of a second, about 20 times...
Laser Polarization Controlled
CAMBRIDGE, Mass., April 13, 2009 -- Lasers with controlled polarization were demonstrated for the first time through the integration of the polarizer on the laser facet, an innovation that could open new applications in photonics and communications. Harvard Univerity and Hamamatsu...
Ulissi Wins DoE Fellowship
Mar 31, 2009 — Zachary Ulissi, a University of Delaware senior double majoring in chemical engineering and physics, has received a Department of Energy (DoE) Computational Science Graduate Fellowship that will total $250,000 over the next four years. During his...
Products, Tech Debut at OFC
SAN DIEGO, March 26, 2009 -- A number of new optical communication technologies and capabilities, particularly those for 40 Gb/s and 100 Gb/s optical links, were unveiled by companies such as Finisar, JDSU, NeoPhotonics, Bookham and Agilent Technologies this week during the...
Polarizers Spy Perilous Chems
CHICAGO, March 13, 2009 – Remote chemical detection is typically done using a technique called laser-induced breakdown spectroscopy (LIBS). This method enables chemists to analyze the composition of a suspected bomb without actually touching it. The LIBS technique is...
Triphoton Squeezed to Limit
TORONTO, Jan. 7, 2009 -- A new technique squeezes light to the fundamental quantum limit, a finding that has potential applications for high-precision measurement, next-generation atomic clocks, novel quantum computing and our most fundamental understanding of the universe....
OPTICAL DESIGN
Jan 1, 2008 — Based on a SPIE professional course, the book Optical System Design, Second Edition, presents techniques and diagrams that illustrate major design procedures. The 624-page resource features new chapters on polarization, diffractive optics,...
Cleveland Crystals: Small Firm with a Big Role in the Laser Industry
HIGHLAND HEIGHTS, Ohio, Aug. 28, 2007 -- Cleveland Crystals Inc. is a small company that plays a very large role in the laser industry, thanks to its unparalleled ability to grow high-quality crystals for laser, electro-optics and laser fusion applications. Crystals are fascinating...
'Optics on a Chip' Melds Photonic Circuitry, Silicon
CAMBRIDGE, Mass., Feb. 7, 2007 -- Using microphotonics, researchers have split the light from an optic fiber in an integrated, on-chip way, controlled the random polarization of the two beams and then reconnected them. The breakthrough in "optics on a chip" technology could lead to...
Johan Holm Honored by Danish Optical Society for PING Gratings
Dec 6, 2006 — Johan Holm has received the DOPS prize from the Danish Optical Society for developing Ibsen Photonic's polarization-independent fused-silica telecom gratings. Ibsen Photonics is a Farum, Denmark-based maker of phase masks and transmission gratings...
Output Beam from Fiber Laser Is Radially Polarized
Dec 1, 2006 — A radially polarized laser beam, in which the electrical field is always along a line from the center, like the hands on a clock, is useful in particle trapping and acceleration, as well as in high-resolution microscopy. Researchers have previously...
