About the Workshop

Following SPIE Photonics West, the largest Photonics event of the year, as well as SPIE Electronic Imaging, a team of US and Danish experts will host a research focused two-day workshop on the development of Photonic Technologies from device level to application level in Communications and BiophotonicsInnovation Center Denmark is hosting the workshop at The Center for Information Technology Research in the Interest of Society (CITRIS), University of California at Berkeley, from January 30th - January 31st 2012.



Photonic technologies

Photonics technologies will impact most areas of our lives, revolutionizing societies and industries around the globe, according to Photonic 21 platform, photonic technologies will enable:

  • Multi-terabit capacity information networks, able to leverage exciting new products and sophisticated services that fully exploit this connectivity

  • Providing solutions for dramatically reducing global energy consumption of our future telecommunication systems

  • Innovative laser processes for example, through improving the efficiency of photovoltaic devices and enabling higher capacity energy storage devices, both these being key requirements for future electric cars and lightweight vehicles

  • Radical new approaches to healthcare by Biophotonic technologies moving from the current, cost-intensive treatment after onset of a disease, to the detection and prevention of the disease at the earliest possible stage. This offers greater patient survivability, less intensive treatment regimes, and significantly reduced post-treatment care costs

  • The transition in lighting from incumbent technology to low energy consumption, digital technology, built around LEDs, OLEDs, sensors and microprocessor intelligence

  • Photonic approaches for display, sensing and imaging will contribute to a greener environment by advanced pollution detection, and enable higher levels of security and safety

During this workshop, experts from industry and academia will present latest results in photonic technologies for nanolasers, biophotonics, optical communication systems for hybrid wireless/wired access networks and video communication.

Hybrid optical fiber/wireless communication

The next decade is expected to be decisive in the Optical Access Networks and broadband wireless technology market. The explosive demand for communication services that only optical fiber technologies can support is leading engineers, scientists and industry to devise a cost-effective solution to support Gigabit connectivity in a scalable way. It is not just the enterprise who is requesting ultra-broadband VPN connectivity between its data centers, or residential customers willing to use 3D immersive applications. It is the 4G broadband cellular data service, a principal contributor to this phenomenon, as the same optical access infrastructure can provide the means to boost the reach of next generation wireless networks. Thus, hybrid optical fiber/wireless communication technology has gained momentum, where radio signals can be effectively carried over an existing optical-fiber infrastructure (saving “last mile” costs).

Recent developments in photonic technology and network protocols may help to cope with the demand of building hybrid optical fiber/wireless communication networks by introducing new optical components and system in the design. However, there is a general consensus that such next generation hybrid access networks should not just provide lots of bandwidth. The designs must be driven also by principles of flexibility, scalability, availability, environment-friendliness and security. Thus, photonic technologies featuring re-configurability, remote operation, energy efficiency and protection are expected to cause a quantum leap in the way broadband wired/wireless access is delivered.


Video communications
Video and related visual services constitute the major driver for high bandwidth network connections. Today IPTV, video-on-demand, peer-to-peer video such as YouTube, video conferencing are all high bandwidth applications experiencing a dramatic growth rate. Social networks in various forms are also embracing visual communication. In the future super HD, 3D TV and video applications will continue the trend of increasing bandwidth demands of visual communication. The display of 3D using stereo or autostereoscopic techniques with and without glasses, respecively, posses a number of challenges and open questions. Visual communication is experiencing an increased diversity and complexity also leading to issues of managing distributed resources and using the potential of cloud computing.



Light’s ability to carry information has placed optics at the forefront of scientific revolutions, from Galileo’s telescopic observations of heavenly bodies to Leeuwenhoek’s investigations of the micro-cosmos. Modern optics and photonics can exploit light not only to perform passive observations but also to interactively control the phenomena. In this respect, the capacity to mould the properties of light is a vital ingredient as it enables us to control light’s interaction with matter. Using light as our eyes and hands into microscopic phenomena can provide critical boost in biomedical investigations. This is needed for advancing biology and medicine into the 21st century calling for new tools that can help tackle challenging biomedical frontiers. From enhancing health to extending life, biomedical research is examining conditions that afflict humans, from the leading causes of death like cardiovascular diseases and cancer, to rising threats like diabetes that though manageable, have prolonged impact on the quality of life.

 Biophotonics is addressing this exciting interdisciplinary research that explores light-based technologies for life-sciences and medicine. The term originates from the ancient Greek words ‘bios’ and ‘phos’ that means life and light, respectively, and thus refers to the unique interplay between biological matter and photons. Biophotonics ultimately aims for an ever-improving health care system, reducing health-care costs, personalizing health care and strive to address the new challenges of the human ageing process, which seems to make us more susceptible to diseases and systemic failures that effectively puts a “best before” date on our life and vitality. Moving forward in this field requires tools for advancing fundamental knowledge that can, subsequently, contribute to the development of next generation tools and technologies for elevating the human condition. Biophotonics typically play important yet secondary roles by providing enabling tools in many applications and the biomedical field is no exception. In many cases, light’s capacity for carrying information can also here play an important role. 



The organizers are from two of the foremost research groups within the field, namely The Center for Information Technology Research in the Interest of Society (CITRIS), University of California at Berkeley (UCB), Stanford University, the Department of Photonics Engineering at the Technical University of Denmark (DTU) and Innovation Center Denmark.


DTU Fotonik and Aalborg University

Researchers from DTU Fotonik have an outstanding track in photonic technologies applied to communications, bio-photonics and video communications. The Institute of Electronics at Aalborg University in Denmark is a well-established institution worldwide in the wireless research area.


The Center for Information Technology Research in the Interest of Society (CITRIS)

CITRIS creates information technology solutions for many of our most pressing social, environmental, and health care problems. CITRIS was created to “shorten the pipeline” between world-class laboratory research and the creation of start-ups, larger companies, and whole industries. CITRIS facilitates partnerships and collaborations among from numerous departments at four University of California campuses (Berkeley, Davis, Merced, and Santa Cruz) with industrial researchers.
