High-Power, High-Efficiency VCSELs Pursue the Goal
Feb 1, 2005 — At Princeton Optronics Inc., we intend to meet the goals of the SHEDS program using vertical-cavity surface-emitting lasers (VCSELs). These devices differ from edge-emitting lasers in that their output beam is perpendicular to the top surface of the device instead of parallel to it. Unlike an edge emitter, a VCSEL’s maximum operating power is not limited by catastrophic optical damage of the exit aperture because its aperture is much larger and its PN junction does not intersect the
Superpolishing Deep-UV Optics
Feb 1, 2005 — Demanding ultraviolet laser applications, such as microlithography and lasik, are driving the need for coated optics that deliver superior performance and longer lifetimes. Tremendous advances have been made in both areas in recent years, and to...
Quantum Cascade Lasers: Valuable New Tools for Laser Spectroscopy
Feb 1, 2005 — Semiconductor lasers emitting in the mid-infrared spectral range between approximately 4 and 13 μm are attractive for a number of applications, such as trace-gas sensing, production and environmental control, medical diagnostics, and free-space...
Miniature Deformable Mirrors Bring Adaptive Optics Within Reach
Feb 1, 2005 — In 1953, astronomer Horace W. Babcock of California Institute of Technology in Pasadena proposed a method to compensate for atmospheric and figure aberrations in the optical path of telescopes. In his approach, a rotating knife edge placed in front...
Breaking the Single-Cycle Barrier
Feb 1, 2005 — From Fourier theory, we know that any periodic shape may be formed by combining sinusoidal waves with prescribed amplitudes, frequencies and relative phases. Functions such as a square or sawtooth wave require frequencies covering several octaves of...
Slower Growth Forecast for Optical Microscopes
Feb 1, 2005 — You can’t fight physics. Despite the continued and great advances made in optical microscopy over the more than 300 years since Antonie van Leeuwenhoek first presented his observations of bacteria in the Royal Society of England’s Philosophical...
Single-Chip Microsystem Cuts Atomic Force Microscopy Down to Size
Feb 1, 2005 — Scanning relatively large samples with commercially available atomic force microscopes (AFM) often can be time-consuming because it is performed serially and because the scanning range is limited. Using lasers to detect cantilever deflection adds to...
Probe Brings Higher Throughput, Resolution to Near-Field Microscopy
Feb 1, 2005 — A team at the University of Alberta in Edmonton, Alberta, Canada, recently evaluated novel designs for near-field scanning optical microscope probes that provide both high throughput and high resolution. The results of the work suggest that...
For Atomic Force Microscopy, the Beat Goes On
Feb 1, 2005 — Researchers have found dynamic force microscopy, or atomic force microscopy (AFM), useful for tracing surfaces on an atomic scale. The technique even may be capable of following biological samples in real time as they twist and turn. The difficulty...
When the Chips Are Down, It's Microscopy to the Rescue
Feb 1, 2005 — Integrated circuits are modern miracles, cramming tens of millions of transistors into thumbnail-size chips. But there’s a dark lining to this silver cloud — one that a terahertz microscopy technique under investigation by scientists at Okayama...
Report Predicts Huge Growth for Nanophotonic Devices
Feb 1, 2005 — The worldwide market for nanophotonic devices is expected to escalate from $420.7 million in 2004 to $9.33 billion in 2009, with an average annual growth rate of 85.8 percent. The figures are taken from the RGB-314 report "Nanotechnology for...
