Achieving Optimum LED Performance With Quantum Dots
The invention of blue LEDs and the subsequent rapid rate of development of new phosphor and down-converting technologies have enabled the phenomenal growth of all LEDs in general lighting applications. White LEDs initially employed the use of a blue LED combined with a single phosphor with broad yellow emission. However, the light quality provided by this relatively simple solution was less than satisfactory, particularly in the red part of the visible spectrum. But more recently, new phosphors and phosphor combinations (green-yellow plus red) have been developed to provide a higher quality of light.

Nonlinear Light Manipulation Could Provide Basis for Optical Nanodevices
Ultrafast nanoantenna switching between different light-scattering modes, caused by the interaction between an intense laser pulse and the silicon of a nanostructure, could lead to devices that would enable ultrafast all-optical signal processing. To demonstrate ultrafast nanoantenna switching, researchers from ITMO University and the Moscow Institute of Physics and Technology (MIPT) manipulated the optical properties of a nonlinear silicon nanoantenna.

Portable Microscope Could Speed Sepsis Detection
A portable microscope, developed as part of a scalable, point-of-care, label-free microarray platform, may offer more rapid detection of sepsis and other infections caused by bacteria, ultimately saving millions of lives each year. The device combines photonics technology, microfluidics and molecular biology to produce sample-to-result processing up to 50 times faster than current testing techniques, which can take as long as 24 hours to achieve similar results.

3D Laser Technology Designs Microscopy Tips at Nanoscale
Mechanically stable atomic force microscopy (AFM) tips with arbitrary shapes can now be added to existing AFM cantilevers using 3D direct laser writing technology based on two-photon polymerization (TPP). TPP, a 3D printing process that provides structuring with extremely high resolution, could offer the ability to design optimal tips and probes with significantly enhanced resolution, leading to more options for analyzing samples.

ICALEO 2016
October 16-20, 2016 - Sheraton San Diego - San Diego United States
The International Congress on Applications of Lasers & Electro-Optics (ICALEO®) has a 34 year history as the conference where researchers and end users meet to review the state-of-the-art in laser materials processing, laser microprocessing, and nanomanufacturing as well as predict where the future will lead. From its inception, ICALEO has been devoted to the field of laser materials processing at macro, micro and nanoscales and is viewed as the premier source of technical information in the field. This year’s featured sessions include diode lasers for processing and pumping, laser process monitoring and control, laser processing of biological materials, lasers in nanotechnology and environmental technology, laser hybrid processing, laser manufacturing for alternative energy sources and laser business development.
