Research & Technology News
Advances Lead to Miniature Supercontinuum Sources
Oct 1, 2004 — Supercontinuum sources are finding increasing use in applications that require a source with very broad spectral bandwidth and high spatial brightness. A common method of generating supercontinuum light has involved the coupling of the output from a high-power femtosecond laser into a photonic crystal, or holey, fiber, in which a variety of nonlinear optical effects contribute to extreme spectral broadening. Although effective, the use of this type of pump source results in a complicated and...
An Organic Field-Effect Transistor Emits Ambipolar Light
Oct 1, 2004 — A new light-emitting field-effect transistor suggests the possibility of electrically pumped organic lasers, potentially prompting investigators to consider novel approaches to multifunctional field-effect devices. A group of researchers from the...
Cool Tunable Laser Suitable for Microscopy
Oct 1, 2004 — A team of scientists at the State University of New York at Albany in Colonie and at the New York state Department of Health in Albany has demonstrated an inexpensive excitation method for applications in confocal microscopy. The scientists exploit...
Efficient Side-Pumping Scheme Excites Short Fiber Lasers
Oct 1, 2004 — Fiber lasers based on low-melting-point glasses can accept much higher doping levels -- sometimes as high as 20 percent by weight -- than conventional silica-glass fiber lasers. Such high levels open the possibility of fiber lasers whose length is...
Femtosecond Lasers Fabricate Improved Optical Waveguides
Oct 1, 2004 — Many laboratories around the world are investigating the use of femtosecond lasers for fabricating optical waveguides. Recently, scientists in a US laboratory employed femtosecond lasers to create waveguides in poly(methyl methacrylate) (PMMA),...
How to Save Fiber from 'The Fuse'
Oct 1, 2004 — Fiber fuse is a catastrophic effect that occurs when an imperfection in the fiber precipitates heating and the local temperature approaches 1000 °C. At that elevated temperature, laser radiation propagating through the fiber is strongly absorbed,...
Liquid Used as Lens for Miniature Cameras
Oct 1, 2004 — As cell phone cameras and other optical devices become smaller and smaller, the lenses become more complex. When the surface-to-volume ratio increases, so does friction, making it difficult to fabricate tiny lenses with moving parts. As a possible...
Mode-Locked Fiber Laser Emits Simultaneous Pulse Trains at Three Wavelengths
Oct 1, 2004 — Modern fiber optic telecommunications systems employ wavelength division multiplexing (WDM), in which multiple wavelengths of light carry information through the optical fibers. Although nearly all deployed systems use multiple transmitting lasers,...
Mode-Locked Laser Has Potential as OC-768 Transmitter
Oct 1, 2004 — A research group at Massachusetts Institute of Technology's Lincoln Laboratory in Lexington, Mass., has designed, built and operated a 40-GHz mode-locked hybrid fiber/semiconductor laser that has potential as the transmitter in next-generation...
Nanodots: No Assembly Required
Oct 1, 2004 — At North Carolina State University in Raleigh, two scientists have demonstrated a laser-assisted nanostructure self-assembly method that yields arrays of uniformly sized nickel nanodots in matrices of aluminum oxide and titanium nitride. They...
Polymer Holey-Fiber Laser Is Easy to Make
Oct 1, 2004 — Solid-state dye lasers, in which the dye is dissolved in a solid host rather than in a liquid solvent, have several advantages over conventional liquid dye lasers, including compactness, robustness and the absence of flammable and volatile organic...
Thermally Actuated Fabry-Perot Filter Tunes Across C- and L-Bands
Oct 1, 2004 — A tunable filter at the output of a semiconductor laser could tune the laser's output across a range of wavelengths. Such a tunable laser would be invaluable in fiber optic communications systems because it could not only reduce the number of spare...
DNA Forms Molecular Photonic Wire
Sep 1, 2004 — Scientists from the University of Bielefeld in Germany and the University of Twente in Enschede, the Netherlands, have demonstrated that standard fluorophores and strands of DNA may be combined to form molecular photonic wires that operate by...
Fiber Polarizer Utilizes Birefringence in Photonic Crystal Fiber
Sep 1, 2004 — Today's fiber optic systems, such as fiber lasers and fiber-based telecom networks, are often forced to use a combination of fiber and bulk optical components because many optical functions, such as polarizers, couplers, filters and mirrors, cannot...
Laser-Assisted Process Grows Sharp Tips
Sep 1, 2004 — Sharp tips coated with diamondlike carbon have potential applications in field-emitter arrays, scanning spreading resistance microscopy and nanofabrication techniques. Reporting in the Aug. 9 issue of Applied Physics Letters, researchers at the...
Lasers Induce Fast Spin Reorientation in Antiferromagnets
Sep 1, 2004 — Unlike common ferromagnets used in everything from compasses to spintronics, antiferromagnets still have fairly limited application potential, in part because of the lack of understanding of the magnetization process for such materials. Now...
Light Moves Water Droplets
Sep 1, 2004 — A team at Arizona State University in Tempe reported in the Aug. 26 issue of Journal of Physical Chemistry B that a nanostructured surface morphology similar to that of lotus leaves imparts the ability to move 15-µl droplets of water using light....
Metallorganic Vapor Phase Epitaxy Yields InSb Photodiodes for Focal Plane Arrays
Sep 1, 2004 — Researchers at Soreq NRC in Yavne and Semi Conductor Devices in Haifa, both in Israel, have reported the fabrication of InSb photodiodes by metallorganic vapor phase epitaxy. The development promises to enable the production of mid-IR focal plane...
Passive Stabilization Technique Tames Unruly Mode-Locked Laser
Sep 1, 2004 — There is a delicate balance between too much saturable absorption and too little when passively mode-locking a laser. Too little absorption yields unstable mode-locking or, worse, fails to mode- lock the laser at all. Too much causes the laser to...
Plastic Waveguides Display Laser Emission
Sep 1, 2004 — A group of scientists at Trinity College in Dublin, Ireland, and at Tohoku University in Sendai, Japan, has achieved near-infrared laser emission from a polymer waveguide doped with an organic dye. The work promises applications in the development...
Something Old, Something New: German Lab Marries Ring and Disk
Sep 1, 2004 — One of the prime patents on the nonplanar ring oscillator (NPRO) expired last month, an occasion its inventors celebrated with a small party. On the other hand, the thin-disk laser is just beginning its career in the commercial marketplace....
Thulium Laser Enables Single-Frequency Oscillation in New Spectral Region
Sep 1, 2004 — Single-frequency fiber lasers have been developed in the 1.1-µm spectral region (based on ytterbium active ions) and in the 1.5-µm region (based on erbium active ions), but, recently, scientists in Denmark developed what they believe is the first...
Tunable Femtosecond UV Pulses Produced by Second-Harmonic Generation
Sep 1, 2004 — The measurement of extremely fast physical and chemical phenomena requires femtosecond pulses such as those generated in the infrared by Ti:sapphire lasers. However, ultrafast experiments with many materials require tunable femtosecond pulses in the...
Eye-Safe Laser Generates 7 W of Average Power
Aug 1, 2004 — Eye-safe lasers with output in the 1.5-µm regime are in demand for rangefinding, lidar and other remote-sensing applications. Most of them have depended on awkward nonlinear optics or on complex cross-excitation pumping schemes to generate 1.5-µm...
Hollow Fiber Delivers Distortion-Free Femtosecond Pulses
Aug 1, 2004 — Multiphoton fluorescence is an important technique for analyzing living tissue, and fiber optic delivery of the femtosecond pulses enables useful instruments such as miniature microscopes and multiphoton endoscopes. A difficulty generally arises,...
