December 2013 Press Release


"Civilization would not exist without Light, light from our Sun and light from the focused and coherent lasers which now have become an important part of our daily lives-from scanning packages at supermarkets, to eye surgery, and to IT communications across oceans. The International Year of Light will surely raise awareness of these powerful discoveries and their present wide-ranging, light-based technologies which are significant contributors to the world market. As importantly, the International Year of Light will inspire future discoveries and applications for one of the most important element of our existence, Light." -- Dr. Ahmed Zewail, Linus Pauling Chair, Professor of Chemistry and Professor of Physics; Director, Physical Biology Center for Ultrafast Science & Technology, California Institute of Technology, USA

Light for the Future:
The science and technology of light are essential for the future development of humankind, and in the search of solutions to solve global problems in sustainability and healthcare through international cooperation. We hope that International Year of Light will increase global awareness of the central role of light in human activities through optics and photonics, and that the brightest young minds continue to be attracted to careers in this field.

Light-based Industries: Industries based on light are major economic drivers, and the many applications of light-based technologies have revolutionized and impacted society through medicine, communications, entertainment and culture.

Light-based technologies directly respond to the needs of humankind by providing access to information, promoting sustainable development, and increasing well-being and standard of living -- perfect examples include the inexpensive solar-powered solid-state lighting that has replaced toxic kerosene for indoor use in some developing regions, remote sensing from space that tracks crop health, major storms, and underground water sources, and non-invasive screening of infants for life-threatening breathing or digestive conditions.
