Nanotechnology will be a major topic, as nearly 6,000 researchers gather at the leading conference on electro-optics, lasers and light waves in early May.

Nanoneedles for ‘AFM on a Chip’ Discussed at 2008 CLEO/QELS

Nano is featured at the 2008 Conference on Lasers and Electro-Optics/Quantum Electronics and Laser Science Conference


The 2008 Conference on Lasers and Electro-Optics/Quantum Electronics and Laser Science Conference (CLEO/QELS and PhAST) will be held May 4-9 in San Jose, Calif.

Notably, University of California (Berkeley) researchers will discuss their work on how nanoscale needles could lead to the construction of lasers and AFM (atomic force microscopes) directly on silicon. Some believe that AFM arrays, besides speeding up the recording of nearly atomic-resolution images of surfaces, might be used to create a new form of data storage by influencing the atoms in the sample.

The team will discuss how they have grown GaAs structures into the shape of narrow needles, which emit light with high brightness. The paper is entitled, “Bright Photoluminescence from GaAs and InGaAs Nanoneedles.”

Other Nano-related CLEO/QELS and PhAST Topics include:
  • -- Status and Performance of the National Ignition Facility (world’s largest laser system for the high-energy density area,
  • -- In-vivo Cellular Level Imaging Using Nonlinear Optical Microendoscopy
  • -- Superresolution Imaging in Live Bacterial Cells by Single-Molecule Active-Control Microscopy
  • -- Optical Microchip Detection of Nuclear Magnetic Resonance (NMR and MRI on a microchip)
