JTuI24<br />

Fabrication of Low Contrast Homogenous<br />

Guided Mode Resonance Filters, Aaron Pung 1 ,<br />

Menelaos Poutous 1 , Zach Roth 1 , Eric Johnson 1 ;<br />

1<br />

UNCC, USA. This paper presents a narrow<br />

spectral filter based on a homogeneous Silicon<br />

Dioxide structure with a periodic array of air<br />

holes. Theoretical and experimental results are<br />

provided for a resonant structure with a 6 nm<br />

spectral width at 1.591μm.<br />

JTuI25<br />

Realization of small footprint microring reflectors,<br />

Amir Arbabi 1 , Young Mo Kang 1 , Lynford L.<br />

Goddard 1 ; 1 Electrical and Computer Engineering,<br />

Univ. of Illinois at Urbana-Champaign, USA. We<br />

present design, fabrication and characterization of<br />

a single wavelength narrow-band reflector made<br />

by integration of a DBR inside a ring resonator. The<br />

DBR covers half of the ring’s circumference and is<br />

only reflective at one ring resonance.<br />

JTuI26<br />

Experimental Demonstration and Simulation<br />

of Lossless Metal-Free Integrated Elliptical<br />

Reflectors for Waveguide Turnings and Crossings,<br />

Xiangyu Li 1 , Fang Ou 1 , Zhenyu Hou 1 , Yingyan<br />

Huang 2 , Seng-Tiong Ho 1 ; 1 Department of Electrical<br />

Engineering and Computer Science, Northwestern<br />

Univ., USA; 2 OptoNet. Inc, USA. Novel on-chip<br />

waveguide turnings and crossings based on<br />

metal-free elliptical reflectors are simulated and<br />

demonstrated. 1µm-wide waveguide case gives<br />

half the loss in elliptical reflector turn (16% loss)<br />

compared to plane mirror turn (30% loss).<br />

Polarization Dependence of Facet Reflectivity<br />

in Rectangular Submicron Waveguides, Todd<br />

Subramaniam Kanakaraju 3 , Christopher Richardson<br />

3 , Jacob B. Khurgin 4 ; 1 Naval Research Lab, USA;<br />

2<br />

Univ. of Tulsa, USA; 3 Lab for Physical Sciences,<br />

USA; 4 Johns Hopkins Univ., USA. We measure and<br />

theoretically describe the polarization anisotropy<br />

of the facet reflectivity in rectangular subwavelength<br />

waveguides. This effect is increasingly<br />

impacting integrated optical devices as the lateral<br />

size scale shrinks.<br />

Modal Formulation for Scattering on the<br />

Absorbing Silicon Nanowire Arrays for Photovoltaic<br />

Applications, Kokou B. Dossou 1 , Lindsay<br />

C. Botten 1 , Ara A. Asatryan 1 , Björn C. Sturmberg 2 ,<br />

Michael A. Byrne 1 , Christopher G. Poulton 1 , Ross C.<br />

McPhedran 2 , C. Martijn de Sterke 2 ; 1 Department of<br />

Mathematical Sciences, Univ. of Technology, Sydney,<br />

Australia; 2 School of Physics, Univ. of Sydney, Australia.<br />

We develop a modal method for modeling<br />

scattering off absorbing silicon nanowire arrays<br />

for photovoltaic applications. This semi-analytic<br />

approach allows the efficient, accurate calculation<br />

of absorption and gives insight into absorption<br />

mechanism.<br />

JTuI29<br />

Scattering Performance of Plasmonic Nanorod<br />

Antennas: An Accurate and Fast Computational<br />

Scheme, Arash Rashidi 1 , Hossein Mosallaei 1 , Raj<br />

Mittra 2 ; 1 Electrical and Computer Engineering,<br />

Northeastern Univ., USA; 2 Electrical Engineering,<br />

Pennsylvania State Univ., USA. A fast and efficient<br />

computational scheme to characterize scattering<br />

from plasmonic nanorod antennas employing<br />

macro basis functions is introduced. This is a<br />

physics-based numerical paradigm with significant<br />

impact on computational nanophotonics.<br />

JTuI30<br />

Gain and noise in long-range surface plasmonpolariton<br />

amplifiers, Israel De Leon 1 , Pierre<br />

Berini 1,2 ; 1 SITE, Univ. of Ottawa, Canada; 2 Physics,<br />

Univ. of Ottawa, Canada. An analysis of gain and<br />

noise in a long-range surface plasmon amplifier<br />

is presented. The amplifier incorporates a gain<br />

medium in the form of LDS821 dye molecules<br />

in solution.<br />

JTuI31<br />

Thin Substrates for Enhanced Metamaterial<br />

Sensing Applications, Sher-Yi Chiam 1,2 , Ranjan<br />

Singh 3,4 , Weili Zhang 4 , Andrew A. Bettiol 1 ; 1 Physics,<br />

National Univ. of Singapore, Singapore; 2 NUS High<br />

School of Math and Science, Singapore; 3 School of<br />

Electrical and Computer Engineering, Oklahoma<br />

State Univ., USA; 4 Materials Physics and Applications<br />

Division, Los Alamos National Lab, USA. We<br />

show that metamaterials on thin substrates exhibit<br />

great sensitivity to changes in their dielectric environment.<br />

They thus show excellent potential<br />

for sensing applications as the analyte film can be<br />

applied on the substrate side.<br />

JTuI32<br />

optically-induced refractive-index gradient,<br />

Zhuoyi Ye 1 , Sheng Liu 2 , Cibo Lou 1 , Peng Zhang 3 ,<br />

Chen 1,3 ; 1 TEDA Applied Physics School,, Nankai<br />

Univ., China; 2 School of Science, Northwestern<br />

Polytechnical Univ., China; 3 Department of Physics<br />

and Astronomy, San Francisco State Univ., USA.<br />

We show how to enhance, reduce, and completely<br />

suppress the acceleration of Airy beams in gradedindex<br />

media. By engineering the refractive-index<br />

gradient, active bending control of the Airy beams<br />

is realized, relevant to various environments.<br />

Photonic Band Gap in 3D Network Structures<br />

with Short-range Order, Seng Fatt Liew 1 , Jin-Kyu<br />

Yang 2 , Heeso Noh 1 , Carl Schreck 3 , Corey S. O’Hern 4,3 ,<br />

Hui Cao 1,3 ; 1 Applied Physics, Yale Univ., USA; 2 Optical<br />

Engineering, Kongju National Univ., Republic<br />

of Korea; 3 Physics, Yale Univ., USA; 4 Mechanical<br />

Engineering, Yale Univ., USA. We show numerically<br />

a significant depletion of the density of optical<br />

states in disordered three-dimensional network<br />

structures. The pseudo photonic band gap is likely<br />

produced by short-range order and uniformity of<br />

local topology.<br />

JTuI34<br />

Advanced and delayed optical images through<br />

single and coupled image resonators, Parvin<br />

Sultana 1 , Takahiro Matsumoto 2 , Makoto Tomita 1 ;<br />

1<br />

Physics, Shizuoka Univ., Japan; 2 Research and<br />

Development Center, Stanley Electric Corporation,<br />

5-9-5 Tokodai, Japan. We propagated transverse<br />

two dimensional images encoded on optical pulses<br />

through a frequency window of coupled image<br />

resonator induced transparency. The optical images<br />

are stored and delayed by 10.5 ns.<br />

Near-Field Coupled SRR Structures in the<br />

Terahertz Region, Evren Ekmekci 1,3 , Andrew C.<br />

Boston Univ., USA; 3 Electrical and Electronics<br />

Engineering, Middle East Technical Univ., Turkey.<br />

We present freq. tunable metamaterials using<br />

broadside-coupled SRRs. Freq. tuning, arising<br />

from changes in near field coupling, is obtained<br />

by in-plane displacement between the SRR<br />

layers. A 30μm shift results in a 663GHz freq.<br />

redshift(51% of f 0 ).<br />

Terahertz propagation through free-standing<br />

woven-steel-mesh metamaterials, Cumali<br />

Sabah 1 , Mark D. Thomson 1 , Fanzhen Meng 1 ,<br />

Hartmut G. Roskos 1 ; 1 Physikalisches Institut,<br />

Johann Wolfgang Goethe Univ., Germany. Woven<br />

mesh metamaterials are investigated for THz<br />

frequencies. Pronounced amplitude transmission<br />

with 92% is observed. The spectral positions of<br />

surface-plasmon polaritons agree with the theory<br />

and abnormal group velocities occur between<br />

pass bands.<br />

Giant Goos-Hänchen Effect at Photonic Crystals<br />

Surfaces, Irina Soboleva 1,2 , Valentina Moskalenko 1 ,<br />

Moscow State Univ., Russian Federation;<br />

2<br />

A.N. Frumkin Inst. of Physical Chemistry and<br />

Electrochemistry, RAS, Russian Federation. Giant<br />

Goos-Hänchen effect is detected using TIR<br />

spectroscopy, directly observed in surface electromagnetic<br />

waves at photonic crystals using far-field<br />

optical microscopy visualization and achieves<br />

100-times enhancement.<br />

Circularly-Polarized Resonances at the Photonic<br />

Band-edge of Chiral Liquid Crystal Microcavities,<br />

Luke J. Bissell 1 , Svetlana G. Lukishova 1 , Carlos<br />

R. Stroud 1 ; 1 Inst. of Optics, Univ. of Rochester,<br />

USA. Narrow, circularly-polarized microcavity<br />

resonances were observed for the first time in the<br />

fluorescence at the photonic band-edge of glassy<br />

chiral liquid crystal microcavities both undoped<br />

and doped with quantum dots irradiated by a<br />

cw-laser beam.<br />
