MQ1 1:30 PM - 2:00 PM (Invited)
Coupled Ring Resonators: Physical
Effects and Potential Applications,
C. Ciminelli, F. Dell’Olio, C. E. Campanella and
M. Armenise, Politecnico di Bari, Bari, Italy
Main physical phenomena occurring in coupled
ring resonators and their most promising applications
in the field of buffers for optical
interconnects, nonlinear optics, angular velocity
sensing, and group velocity manipulation are
reviewed in the paper.
MR1 1:30 PM - 2:00 PM (Invited)
Integrated Lab on Chip for Detection of
Cells and Micro-Organisms, E. Salm,
C. Duarte and R. Bashir, University of Illinois at
Urbana-Champaign, Urbana, IL, USA
We aim to take ‘lab-on-a-chip’ further by introducing
‘lab-on-a-transistor’. We developed a
heating technique that allows transistors to act as
electrically addressable, individual heaters. To
demonstrate this technique, DNA denaturation in
sub-nanoliter droplets is shown.

S. P. Khanna, L. H. Li and E. H. Linfield,
University of Leeds, Leeds, UK
A graded-barrier photovoltaic infrared detector is
reported based on split-off transitions. This
detector showed room temperature operation
with zero-response threshold at ~4 µm and a
long-wavelength peak up to 8 µm at 80 K.

using He Ion Implantation, I. C. Sandall,
C. H. Tan, University of Sheffield, Sheffield, UK,
A. J. Smith and R. M. Gwilliam, University of
Surrey, Guildford, Surrey, UK
We investigate the use of Helium ion implantation
to create resistive regions in InAs, with an
increase in resistivity of seven orders of magnitude
being observed. This has been used to
realize planar photodiodes.
MQ2 2:00 PM - 2:15 PM
Transmission Amplitudes and Modeling
of SNAP Devices, M. Sumetsky, OFS
Laboratories, Somerset, NJ, USA
The transmission amplitudes of SNAP (Surface
Nanoscale Axial Photonics) devices are determined
and applied to investigation of basic
SNAP structures.
MR2 2:00 PM - 2:15 PM
A Point-of-Care Diagnostic Prototype for
High-Throughput, Multiplexed Single-
Virus Detection, A. Reddington, J. T. Trueb,
G. Daaboul, D. S. Freedman, H. Fawcett,
J. Connor and M. Unlu, Boston University,
Boston, MA, USA
A self-contained point-of-care prototype has
been developed using an interferometric technique
for high-throughput single-particle
detection on a simple 2-layer surface. Initial
results show a label-free limit-of-detection of 10 4
PFU/ml in serum for vesicular stomatitis virus.
MS2 2:00 PM - 2:15 PM
Phase of Intermodulation Distortion
Products in High-Linearity Photodiode:
Measurement Technique and Theoretical
Model, Y. Fu, H. Pan, A. Beling, and
J. C. Campbell, University of Virginia,
Charlottesville, VA, USA
The third-order intermodulation distortion products
(IMD3) of the high-linearity InGaAs/InP
photodiode exhibit 180 degree phase changes
around their minima, which can be explained by
a nonlinear responsivity model.
MT3 2:00 PM - 2:15 PM
InAs Quantum Dot Photodetector
Operating at 1.3 µm Grown on Silicon,
I. C. Sandall, J. S. Ng, J. P. R. David, C. H. Tan,
University of Sheffield, Sheffield, UK, T. Wang
and H. Liu, University College London, London,
UK
The optical and electrical properties of InAs
quantum dots epitaxially grown on silicon have
been investigated to evaluate their potential as
photodiodes, avalanche photodiodes (APDs) and
electro-optical modulators operating at a wavelength
of 1300 nm.
MQ3 2:15 PM - 2:30 PM
Modeling Sagnac Effect in Micro
Resonators Using FDTD Method,
R. Novitski, J. K. Scheuer and B. Z. Z. Steinberg,
Tel Aviv University, Tel-Aviv, Israel
We present a novel FDTD method for studying
optics in rotating microrings. We find that in
contrast to commonly thought, the Sagnac
frequency splitting depends on the group index
and not on the effective index.
MR3 2:15 PM - 2:30 PM
Experimental Detection of 1Pico-Molar
Concentration from High-Q Photonic
Crystal Microcavity Biosensors, Y. Zou,
University of Texas at Austin, Austin, TX, USA,
S. Chakravarty, Omega Optics Inc., Austin, TX,
USA, W.-C. Lai and R. T. Chen, University of
Texas at Austin, Austin, TX, USA
We experimentally demonstrate a photonic
crystal microcavity biosensor with 1pM sensitivity.
Radiation loss engineering for high Q and
increased mode overlap with analyte are
combined to achieve the highest sensitivity in
silicon-on-insulator platform.

THz Waveguide, D. Take, M. Shirao,
K. Maruyama, N. Nishiyama, M. Asada and
S. Arai, Tokyo Institute of Technology, Tokyo,
Japan
A novel structure of the optical/THz signal
converter was proposed. By using THz plasmon
waveguide, high conversion rate of optical/THz
signal was estimated. It can be integrated with
optical waveguide and THz RTD oscillator.
MT4 2:15 PM - 2:30 PM
Charge-Compensated High Gain InAs
Avalanche Photodiode, W. Sun, University of
Virginia, Charlottesville, VA, USA
We report an InAs avalanche photodiode with
graded p-doping to compensate the n-type
background doping in the depletion region. The
measured gain, excess noise, and bandwidth are
consistent with Monte Carlo simulation.

We present the design, fabrication, and characterization
of quantum dots-in-a-well infrared
detectors integrated with a planar metamaterial
layer. The resonantly excited metamaterial layer
provides strongly enhanced optical fields and the
increased photocurrent.
