Plenary • Plasmonics: Optics at the Nanoscale Wednesday, May 7, 8:00 a.m.–11:00 a.m., San Jose Civic Auditorium Albert Polman; Center for Nanophotonics, FOM-Inst. AMOLF, Netherlands. The generation, concentration and dispersion of surface plasmons in thin metal films, nanoresonators and metal particle arrays is to be presented. The unique dispersion and mode confinement characteristics of these structures enables control of light at the true nanoscale.
CThLL1 • Plasmonics-Based Design: Combining Surface-Enhanced Raman and IR Spectroscopies into the Same Structure Thursday, May 8, 4:45 p.m.–5:15 p.m., Marriott San Jose Salon 5 and 6 Naomi Halas; Rice Univ., USA. Plasmonic nanostructures are useful for providing high-intensity fields at metal surfaces for surface enhanced spectroscopies. Plasmon hybridization principles are used to design substrates that enhance both Raman and Infrared absorption spectroscopy on the same structure.
CNN recently spoke to Naomi Halas about nanotechnology and her work on nanoshells, tiny particles that may hold the key to curing cancer. CWM3 • Detection of Neural Cell Activity Using Plasmonic Gold Nanoparticles Wednesday, May 7, 5:15 p.m.–5:30 p.m., Marriott San Jose Salon 1 and 2 Jiayi Q. Zhang¹, Tolga Atay¹, Arto V. Nurmikko²; ¹Physics Dept., Brown Univ., USA, ²Div. of Engineering, Brown Univ., USA. Metal nanoparticles have been studied intensively for their applications using localized surface plasmon polariton (SPP) resonance. We have demonstrated for the first time that using gold nanoparticles, one can detect electrical activities from the neurons.
QMD1 • Nanoplasmonics: Subwavelength Waveguides, Resonators and Antennas Monday, May 5, 10:15 a.m.–10:45 a.m., Ballroom A1 and A8 Sergey I. Bozhevolnyi; Aalborg Univ., Denmark. Subwavelength waveguides, resonators and antennas utilizing surface plasmon polariton modes are considered, reviewing recent experimental investigations and demonstrating first examples of ultracompact plasmonic components.
QWF5 • Carrier Multiplication in Semiconductor Nanocrystal Quantum Dots and Solar Energy Conversion Wednesday, May 7, 5:45 p.m.–6:15 p.m., Room C1 and C2 Victor I. Klimov; Los Alamos Natl. Lab, USA. This paper discusses aspects of carrier multiplication (multiexciton generation by single photons) in semiconductor nanocrystals such as its mechanism, competing relaxation channels, ultimate efficiencies for photon-to-exciton conversion and implications of this process in photovoltaics.
CMX1 • Laser Precision Engineering: From Microprocessing to Nanofabrication Monday, May 5, 1:30 p.m.–2:00 p.m., Marriott San Jose Salon 1 and 2 Ming Hui Hong; Data Storage Inst., Agency for Science, Technology and Res. and Dept. of Electrical and Computer Engineering, Natl. Univ. of Singapore, Singapore. Laser precision engineering has advantages of non-contact process, flexible setup and high speed processing. Combined with other advanced processing tools, laser nanofabrication will play a much more important role in the next generation manufacturing.
CMX2 • Laser Direct Write Near-Field Nanopatterning Using Optically Trapped Microspheres Monday, May 5, 2:00 p.m.–2:15 p.m., Marriott San Jose Salon 1 and 2 Euan McLeod; Craig B. Arnold; Princeton Univ., USA. We use Bessel beam optical traps to self-position microsphere objectives near surfaces. Pulsed laser illumination of these objectives is used to perform near-field direct-write subwavelength optical nanopatterning with 100 nm feature sizes.
SC221 • Nano-Photonics: Physics and Techniques Monday, May 5, 9:00 a.m.–12:00 p.m. Axel Scherer; Caltech, USA. This Short Course will start with an introduction to photonic crystals, photonic crystal nanocavities, and lasers fabricated in thin semiconductor slabs containing quantum wells. The characteristics and applications of ultrasmall lasers will be described for spectroscopy, and the opportunities for optical nanocavities in quantum information processing will be reviewed. This will be followed by a description of the integration opportunities of photonic crystal cavities with vertical cavity surface emitting and microdisk lasers. The attributes of high Q micro-toroid cavities will be compared with ultra-small medium Q microfabricated nanocavities.
