Its Applications, Y. Xu, Y. Leng, X. Liang,
J. Liu, R. Li and Z. Xu, Shanghai Institute of
Optics and Fine Mechanics, Shanghai, China
The recent technical progress on the
femtosecond petawatt Ti:sapphire laser are
presented, which include the peak power
(1.26PW) and temporal contrast (~10 11 )
enhancement. Further, the significant applications
achieved from the petawatt laser facility are
summarized.

Fiber-Optic Current Sensors for
Applications in the Electrowinning
Industry and in Electrical Power
Transmission, G. M. Müller, A. Frank,

B. Guelenaltin, ABB Corporate Research Ltd.,
Baden-Dättwil, Aargau, Switzerland
The previously demonstrated inherent temperature
compensation of an interferometric
fiber-optic current sensor is extended to the
cases of large Faraday phase shifts and strong
bend-induced birefringence in the sensing fiber.

Silicon 2R Regenerator, G. Kurczveil,
M. Heck, J. D. Peters and J. E. Bowers,
University of California - Santa Barbara, Santa
Barbara, CA, USA
An optical 2R regenerator is presented. The
device consists of an optical amplifier integrated
with a saturable absorber. Over 3 dB improvement
in the extinction ratio is seen for 1 Gb/s
signals at 1560 nm.

High-Quality InP/ZnS Nanocrystals with
High Photometric Performance and Their
Application to White Quantum Dot Light-
Emitting Diodes, X. Yang, Nanyang
Technological University, Singapore
Full visible range covering InP/ZnS core-shell
nanocrystals with high photometric performance
have been prepared. Making use of these
nanocrystals, we demonstrate a white quantum
dot LED with a high color rendering index of 91.

Phonon-Assisted Nonradiative Energy
Transfer from Colloidal Quantum Dots to
Monocrystalline Bulk Silicon, A. Yeltik,
B. Guzelturk, P. L. Hernandez Martinez and
H. V. Demir, Bilkent University, Bilkent, Ankara,
Turkey
We show nonradiative energy transfer (NRET)
from colloidal quantum dots (QDs) to bulk
silicon using phonon assisted absorption and
demonstrate its physical model to explain
temperature-dependent lifetime dynamics of
NRET in these QD-Si hybrids.

Spectral Beam Combining of High Power
Fiber Lasers, T. Schreiber, N. Haarlammert,
R. Eberhardt and A. Tunnermann, Fraunhofer-
Institute for Applied Optics and Precision
Engineering, Jena, Germany
We review the technique of spectral beam
combining and discuss detailed limitations in the
laser systems used for combination of multiple
cw and pulsed fiber amplifiers to kW average
power and mJ’s of pulse energy.

and J. M. Ballato, Clemson University, Clemson,
SC, USA
Reported here are optical fibers exhibiting significant
longitudinal changes in optical properties
over short lengths. The Brillouin gain is found to
decrease by over 6 dB relative to a standard
optical fiber as a result.

Hybrid Silicon Lasers for Optical
Interconnect, Y. De Koninck, S. Keyvaninia,
S. Stankovic, D. Van Thourhout, G. Roelkens
and R. G. Baets, Ghent University, Gent, Belgium
Hybrid III-V/silicon lasers for short reach optical
interconnect applications need to have a modest
power dissipation and preferably also a small
footprint. Furthermore they should be free of
mode hops even under varying temperature
conditions. In this paper a number of designs
will be discussed that address this set of requirements.

Austin, Austin, TX, USA
We report a novel mid-IR nano-spectroscopy
technique. Absorption is detected by measuring
associated sample expansion. High sensitivity
and spatial resolution are obtained using local
intensity enhancement below a metallic atomic
force microscope tip.
