WQ4 2:15 PM - 2:30 PM
Indirect Modulation of a Terahertz
Quantum Cascade Laser Using Gate
Tunable Graphene, S. Badhwar, University of
Cambridge, Cambridge, UK
We use single layer graphene to indirectly modulate
a THz QCL operating at 2.0 THz. The THz
transmission is controlled by sweeping the
frequency of gate bias on graphene to well
beyond cutoff.
WR3 2:15 PM - 2:30 PM
Event horizon and four-wave mixing in
optical fibers, G. N. Genty, Tampere University
of Technology, Tampere, Finland, M. Erkintalo,
University of Auckland, Auckland, New Zealand
and J. M. Dudley, University of Franche-Comte,
Besancon, France
We discuss the physics of optical event horizons
and clarify how the horizon dynamics can be
naturally interpreted in the framework of wave
mixing between a soliton and a weak linear wave.

X-Cut LiNbO 3 Microwave-Lightwave
Converters Using Patch-Antennas with a
Narrow-Gap for Wireless-Over-Fiber
Networks, Y. N. Wijayanto, H. Murata, Osaka
University, Toyonaka, Osaka, Japan,
T. Kawanishi, National Institute of Information
and Communications Technology, Koganei,
Tokyo, Japan and Y. Okamura, Osaka University,
Toyonaka, Osaka, Japan
X-cut LiNbO 3 microwave-lightwave converters
using patch-antennas with a narrow-gap are
proposed for direct wireless to optical conversion.
Conversion efficiency of the proposed
devices was improved by 6dB for 26GHz bands
compared with z-cut LiTaO 3 devices.

Virtual Contrast Enhancement Intelligent
Illumination Adjustment Processing with
Field Programmable Gate Array based
Camera Systems for Imaging
Applications enhancing Contrast in multi
AOI Applications, M. Rosenberger, Ilmenau
University of Technology, Ilmenau, Germany
Virtual contrast enhancement allows a high
speed illumination sequence set optimization for
high precision measurement tasks. Therefore an
FPGA controls the illumination and processes a
captured image stack inside the camera.
WQ5 2:30 PM - 2:45 PM
Trapping a Terahertz Wave in a Photonic-
Crystal Slab, R. Kakimi, M. Fujita, M. Nagai,
M. Ashida and T. Nagatsuma, Osaka University,
Toyonaka, Osaka, Japan
We trap a terahertz-wave in a photonic-crystal
slab using in-plane resonance. Spectrograms
made from time-domain spectroscopy visualize
the dynamics of trapping successfully.
Absorption is introduced as a test bed for
controlling the trapped wave.
WR4 2:30 PM - 2:45 PM
Controllable Hysteresis Characteristics
via Spatial Gain Overlap in Multimode
Interferometer-based Bistable Laser
Diodes, F. F. Foda and H. A. Bastawrous,
German University in Cairo, Cairo, Egypt
While saturable absorber can control the
hysteresis window width in multi-mode-interferometer
bi-stable laser diodes, spatial gain
overlap showed significant effect on the
threshold currents of the hysteresis window.
WS5 2:30 PM - 2:45 PM
UWB Doublet Pulse Generation Using the
Combination of Parametric Amplification
and Cross Phase Modulation, J. Lee,
Y. M. Chang and J. H. Lee, University of Seoul,
Seoul, Korea
An all-optical, UWB doublet pulse generation
scheme based on nonlinear optical loop mirror
with parametric amplification is experimentally
demonstrated. The scheme is shown to be
capable of producing high quality UWB doublet
pulses
WT4 2:30 PM - 2:45 PM
Smart Multispectral Imager, M. Preissler
and M. Rosenberger, Ilmenau University of
Technology, Ilmenau, Germany
The Multispectral Imager combines parallel
FPGA Hardware with modular and high dynamic
mechanical design. Integrated processing and an
interconnection to all electromechanical parts
enable a real time image correction and
processing with lowest latency time.

P. L. Huang, B.-Z. Hsieh, S.-H. Huang, C.-Y. Yeh,
J.-J. Lin and W.-H. Cheng, National Sun Yat-Sen
University, Kaohsiung, Taiwan
A homogeneously dispersed graphene saturable
absorber employing nano-mica dispersant on
mode-locked fiber laser is proposed. A stable
ultrafast fiber laser with pulses as short as 382 fs
and 3-dB bandwidth of 6.66 nm was obtained.
responses of silicon nanowires are characterized
using a terahertz optical asymmetric demultiplexer
(TOAD) based pump-probe scheme.
Ultra-fast recovery is observed for moderate
pump powers.
