A much appreciated feature of the CLEO®/Europe-IQEC meetings
has always been the symposia that are organized to anticipate on
emerging fields by putting emphasis on fast developing, well
defined topics. Symposia rely on a large fraction of invited
presentations but typically also accept contributed presentations.
Unless the authors object, submissions may be transferred from
"topic areas" to symposia and vice versa

Three symposia have been identified for CLEO®/Europe-IQEC 2007:
JSI - Cryptographic Techniques in Photonics
JSII - Nanophotonics and Metamaterials: From Concepts to Devices
JSIII - Optical Frequency Combs and Applications

JSI - Cryptographic Techniques in Photonics
This Joint Symposium welcomes contributions on any topic
relevant to the application of photonic and optical technologies for
cryptography. Topics include, but are not restricted to, the following:
chaotic emitter and receiver sources; compact and integrated devices; optical chaos cryptography; quantum key distribution; schemes for information encryption; evaluation of transmission characteristics: bit rate, bit error rate, maximum transmission distance, dispersion compensation techniques; synchronization improvements; free-space and fiber implementations; security aspects: evaluation and characterization; information-theoretic security; key distribution; bidirectional communications; exploitation of correlations via public discussion protocol; single photon sources; use of coherent states for cryptography.

JSII - Nanophotonics and Metamaterials: From Concepts to Devices
Nanophotonics and Metamaterials are overlapping areas of
photonics research that have rapidly grown in importance in
recent years. The symposium will be concerned with wavelength
scale and sub-wavelength scale photonics - and, more generally,
with optical structures and devices where the response is
determined by nanoscale features. Interest in metamaterials that
operate at optical frequencies has increased greatly since
deterministic fabrication technology that can produce specific
properties reproducibly has now emerged. The symposium will
cover basic physics, new phenomena, materials properties,
fabrication technologies, modelling, device design and
characterization - applied in a nanophotonics environment. The
symposium will seek to capture the excitement and diversity of
this field by gathering experts and newcomers alike to present
their latest research developments (both fundamental and
applied) in the above-mentioned areas. Submissions that address
specific areas of potential application will be especially welcome.

JSIII - Optical Frequency Combs and Applications
Optical frequency combs based on femtosecond mode-locked lasers have brought about a revolution in optical frequency
metrology, providing a simple and robust means of connecting the
optical and microwave domains of the electromagnetic spectrum.
This has made possible the direct counting of optical cycles, which
is a critical milestone in the creation of next-generation optical
atomic clocks and techniques of precision spectroscopy. Indeed,
the importance of these recent developments, as pioneered by
T.W. Hänsch and J.L. Hall, was recognized in the award of the
2005 Nobel Prize in physics. Beyond applications in precise
time/frequency metrology and tests of fundamental theories, such
combs have opened new research avenues in precise length
metrology, remote ranging and sensing, novel broadband
spectroscopy techniques, and the synthesis of low-noise/low-jitter
waveforms. Moreover, these applications have synergistically
motivated important developments in carrier-envelope stabilized
femtosecond lasers, coherent linking of multiple broadband
sources and nonlinear broadening and frequency conversion
techniques that have now pushed frequency combs into new
spectral regimes from the XUV to far-IR. This joint symposium will
seek to capture the excitement and diversity of this field by
gathering experts and newcomers alike to present their latest
research developments (both fundamental and applied) in the
above-mentioned areas.
