Light: Science and Technology

From gamma rays to radio waves, the spectrum of light provides insights both far-ranging and near, from the origin of the Universe to technologies that have shaped our society. For instance, advanced research in areas such as nanophotonics, quantum optics, and ultrafast science are inspiring new fundamental discoveries and opening new scientific frontiers.

Light-based technologies and photonics directly respond to the needs of humankind by providing access to information, promoting sustainable development, and increasing well-being and standard of living.

Photonics-enabled industries are major economic drivers, and the many applications of photonics have transformed society through improved medicine, communications, and energy production.

Photonics is ubiquitous in our daily lives: from technologies that improve vision and power the Smartphones in our hands, to state-of-the-art technologies that provide us with tools for space observation and fibre optics that help us communicate via the Internet. Photonics is poised to become the key enabling technology of the future.
