Wavelength response of waveguide volume grating couplers for optical interconnects
(Georgia Institute of TechnologyOptical Society of America, 2004-09)The wavelength response of a waveguide volume grating coupler (WVGC) is analyzed for coupling light from a slab waveguide into the superstrate. A leaky-mode approach is used in conjunction with rigorous coupled-wave analysis. ... -
White OLEDs for Displays and General Lighting
(2014-06-06)Junji Kido presents a talk on the recent progress in white OLEDs. In 1993, white-light-emitting OLEDs were developed for the first time. Since then, the performance of white OLEDs has steadily improved and, today, they ... -
Wideband measurements of angle and delay dispersion for outdoor and indoor peer-to-peer radio channels at 1920 MHz
(Georgia Institute of TechnologyInstitute of Electrical and Electronics Engineers, 2003-05)This paper presents spatio-temporal measurements for the peer-to-peer radio channel at a center frequency of 1920 MHz with 140 MHz of radio-frequency bandwidth. The measurements were taken using a spread-spectrum channel ... -
Wiener chaos expansion and simulation of electromagnetic wave propagation excited by a spatially incoherent source
(Georgia Institute of TechnologySociety for Industrial and Applied Mathematics -, 2010)First, we propose a new stochastic model for a spatially incoherent source in optical phenomena. The model naturally incorporates the incoherent property into the electromagnetic wave equation through a random source term. ... -
The X-1 Sigma(+)(g), B-1 Delta(g), and B ` (1)Sigma(+)(g) states of C-2: A comparison of renormalized coupled-cluster and multireference methods with full configuration interaction benchmarks
(Georgia Institute of TechnologyAmerican Institute of Physics, 2005-03)Unusual bonding and electronic near degeneracies make the lowest-lying singlet states of the C2 molecule particularly challenging for electronic structure theory. Here we compare two alternative approaches to modeling ... -
Young modulus dependence of nanoscopic friction coefficient in hard coatings
(Georgia Institute of TechnologyAmerican Institute of Physics, 2003-08)We present an atomic force microscope study of nanoscopic sliding friction on diamond, diamond-like carbon, and on three CrN thin films with varying hardness obtained by different growth temperatures. For the CrN films, ...
