Commercialization in Semiconductor
Based Photonics
Michael Ettenberg, Sensors Unlimited, USA
Just as in Integrated Circuits, in Photonics, advances in semiconductor technology
drive products to lower costs, higher reliability, increased performance and
higher efficiency. However, it takes money to advance manufacturing technology
and large sales volume is needed. Sales volume is, in turn, driven by applications.
During the symposium we will review advances in near infrared detectors and
imaging as well as new applications. We will also discuss super efficient lasers,
tunable lasers and vertical cavity lasers product and their applications.
Michael Ettenberg has worked on III-V materials and
optoelectronic devices for over 25 years. Ettenberg developed the dielectric
mirrors used on all of today's laser diodes. He is presently retired from Sarnoff
Corporation and is an independent consultant. Sarnoff designs and develops new
products for other companies, including OEM suppliers of laser diodes. Ettenberg
is now working with Sensors Unlimited, a leading supplier of near infrared detectors
and systems.

Photonics in Nanotechnology
Steve Brueck, Univ. of New Mexico, USA
Nanotechnology, the use of the unique characteristics of nanoscale structures
in a wide variety of physical systems, is widely recognized as an important
emerging scientific and technological arena. Indeed almost every aspect of the
scientific enterprise is being impacted by developments in nanotechnology. This
presentation will be an overview of two aspects of photonics in nanotechnology:
the use of photons in nanofabrication, and the implications of nanofabricated
materials for photonic devices and systems. In fabrication, optical technology
continues as the dominant manufacturing paradigm for integrated circuits, even
for scales as small as the 45-nm half-pitch node. The possibilities of extending
deep-UV optical lithography even further, and of the advent of new optical techniques,
such as Extreme Ultraviolet Lithography (EUVL), will be covered in this symposium.
Nanostructures in photonics include such diverse subjects as quantum dot semiconductor
materials for sources and detectors; 1-, 2-, and 3-D photonic crystal materials
for waveguides and laser cavities; nanoscale epitaxy as a new paradigm in crystal
growth; and composite materials for negative index and plasmonics.
Steven R. J. Brueck is Professor of Electrical and Computer
Engineering, Professor of Physics and Astronomy and Director of the Center for
High Technology Materials at the University of New Mexico. Prior to joining
the University of New Mexico in 1985, Dr. Brueck was a staff member in the Quantum
Electronics Group at the MIT Lincoln Laboratory. Professor Brueck’s current
research interests are in nanoscale optical lithography–both with liquid
immersion and with nonlinear extensions analogous to frequency doubling in the
time domain–and in a wide variety of applications of this fabrication technology.
These include: photonic crystal resonators and waveguides, infrared metamaterials
for negative index, nanoscale fluidics for biological separations, and directed
self-assembly for extensions of fabrication to the sub-nanometer regime.

Biophotonics Symposium Keynote
Complex Cancer Genomes—Finding Signals in the
Noise
Joe W. Gray, Director, Life Sciences, Lawrence Berkeley
Natl. Lab., USA
Human cancers progress through accumulation of a remarkable number of genomic
and epigenomic abnormalities. In some tumors, thousands of genes may be deregulated
by these abnormalities. Moreover, the spectrum of abnormalities varies considerably
between tumors–even those with similar clinical characteristics. This heterogeneity
frustrates attempts to identify therapeutic points of attack and causes substantial
heterogeneity in individual response. Fortunately, efficient, large-scale genomic
analysis tools and biological resources that allow high-resolution genomic assessment
of sufficiently large numbers of tumors are now available. This is significant
in that recurrent abnormalities can be recognized and assessed biologically.
This presentation will focus on these technologies and on lessons learned from
their application to human breast and ovarian cancers.
Joe Gray majored in Engineering Physics at the Colorado
School of Mines and obtained his Ph.D. in Nuclear Physics from Kansas State
University in 1972. He then joined the Biomedical Sciences Division of the Lawrence
Livermore National Laboratory, moving to UCSF as Professor of Laboratory Medicine
and Radiation Oncology in 1991. He established and headed the Division of Molecular
Cytometry in the Department of Laboratory Medicine until 1997. He was Interim
Director of the UCSF Cancer Center from 1995 to 1997 and is now Program Leader
for Cancer Genetics and Breast Oncology there. He has been Principal Investigator
of the Bay Area Breast Cancer SPORE since 1996. Dr. Gray accepted a position
as Division Director of Life Sciences and Associate Director of Biosciences
at the Lawrence Berkeley National Laboratory in April 2003, and will continue
as a member of the UCSF Cancer Center and as Principal Investigator of the Breast
Cancer SPORE.

Lasers in Manufacturing
Len Marabella, JDS Uniphase, USA
The applications of lasers in manufacturing range from the micron-scale features
in electronics and photonics, to sheet metal welding, cutting in the automotive
industry, and deep penetration welding in shipbuilding. New laser capabilities
have enabled new micro-machining capabilities. Femtosecond lasers provide high
precision, ablative material removal of metals and insulators with essentially
zero damage to the parent material. This leads to new micro-machining capabilities
for via drilling, 3-D nano-processing of photonic components, biochemical IC
chips, and for microfluidic mixers and vasculatures. Ultraviolet and deep UV
lasers enable precision machining for a wide variety of materials. Laser annealing
is being successfully applied to poly-silicon TFT for FPD applications. The
demand for product identification has let to rapid expansion of the laser marking
market. Macro-machining applications continue to expand through new laser technology,
and through growing acceptance by manufacturing industries, especially automotive.
Recent advancements in wallplug efficiency and improved reliability offered
by fiber lasers, disk lasers, and direct diode lasers are having a major impact
in the manufacturing arena.
Len Marabella is currently the Director of R&D
for JDS Uniphase’s Commercial Laser Division, where he is responsible for
the development of new CW, and Q-switched diode pumped solid-state lasers, and
fiber laser products. Prior to joining JDSU in 2002, he managed a variety of
solid-state laser and nonlinear optics development programs during his 21 years
at TRW. This included management of the Precision Laser Machining Consortium
and the development of a 5kW, high brightness, diode pumped solid-state laser
that achieved weld depths in steel of greater than 70mm. He received his PhD
in chemical physics from Indiana University and did post-doctoral research at
MIT.

Photonics is a key enabling technology for many emerging systems for homeland
and national security. The range of applications encompasses visible and IR
imaging, 3-D ladar imaging, IR countermeasures, laser range finders and designators,
chem-bio sensing, OE networking of sensors, directed energy, and a host of others.

Branch at the Army Research Laboratory. His present scope of work is semiconductor
heterostructure optoelectronic physics and component development. During his
tenure in this position, he was also Acting Chief of the Electro-Optics and
