Carmen N. Afonso is a Research Professor at the
Optics Institute of the Spanish Research Council
(CSIC) where, in the eighties, she initiated the
Laser Processing Group which is currently a
20-person group. The research activities of the
Group initially focused on the understanding
and controlling of laser - matter interactions. This
was mainly done through dynamic studies using
real time optical measurements with nano and
picosecond resolution, with particular emphasis
on ultrafast phase transformations for optical data
storage. More recently, research has also focused
on the production of nanostructured materials
with improved responses and their application
to integrated optical devices. The Group is one
of the pioneers in using pulsed laser deposition
for nanostructuring materials and using this
nanostructuring concept for both understanding
interactions in the nanometer scale and optimising
optical response of materials.

Technology, School of Engineering and Information
Technology, Univ. of New South Wales, Australia,
Ctr. for Quantum Computer Technology, Dept. of
Physics, Univ. of Queensland, Australia. We demonstrate the measurement of a “squeezing comb”,
the time-resolved homodyne detection of the first
twelve vacuum squeezing sidebands of an optical
parametric oscillator, and propose its use as a multiplexed quantum communications channel.

Based on a KTP Waveguide, Zachary H. Levine,
Jun Chen, Alexander Ling, Jingyun Fan, Alan
Migdall; NIST, USA. We show that with simple
spectral filtering, the Schmidt number for the

down-conversion in a KTP waveguide equals to
unity to within 0.2%.

David Molnar1,2, Thorsten Schumacher 1,2, Kai
Kratzer1,2, Markus Lippitz1,2; 1Max-Planck-Inst.
for Solid State Res., Germany, 24th Physics Inst.,
Univ. of Stuttgart, Germany. A tiny variation of a
single metal nanoparticle’s dielectric properties has
only a weak influence on the light field. We demonstrate, using optical nano-antenna concepts,
how plasmon hybridization helps to increase the
particle’s influence.
Homodyne Locking of a Squeezer, Michele

Wales, Australia, 2Ctr. for Quantum Computer
Technology, School of Engineering and Information
Technology, Univ. of New South Wales, Australia,

Information Technology, Australian Natl. Univ.,
Australia. Homodyne locking is a new approach
to frequency-locking an OPO-based squeezedvacuum source and its driving laser. It is cheap,
easy to implement, subsequent measurements
are automatically phase-locked, and it is uniquely
a sub-QNL frequency discriminator.
