As the General Chair, it is my pleasure to welcome you to ICO-24 (the 24th General Congress of International Commission for Optics). The ICO General Congress has been one of the most historic and authoritative conferences in the field of optics and photonics since the 1st congress was held in the Netherlands in 1948. Following ICO-13 in Sapporo in 1984, in 2017 Japan will once again host ICO-24: which is to be held at the Keio Plaza Hotel, Shinjuku, Tokyo, from August 21st to 25th. With attendees and delegates from all over the world, ICO-24 will include a wide range of topics on optics and photonics, providing a platform for mutual communication between researchers of different fields linked with the main common theme of “Light for Society”.

Since the discovery of the laser, the field of optical science has expanded to incorporate quantum and nonlinear optics, photonics, nano-optics, semiconductor optical materials science, complex dynamics, and quantum computing etc., and has grown to have technological applications in communications, health, materials processing, renewable energy generation, and energy saving. Optical imaging science also plays an important role in monitoring disaster risks and ecosystem changes due to global warming.

ICO-24 will consist of plenary sessions, oral sessions, poster sessions, and various social events. The plenary session will feature speakers who will share their viewpoints on very relevant topics of present interest and and also their visions and perspectives on future trends. A current list of the inspiring plenary speakers includes Prof. Hiroshi Amano (2014 Nobel Laureate, Nagoya Univ.), Prof. Hiroshi Kajita (2015 Nobel Laureate, The Univ. of Tokyo), Prof. Christopher Dainty (Imperial Col. London), and Prof. James Fujimoto (Massachusetts Inst. of Tech.).

The ICO represents optics and photonics on an international level incorporating 53 national territories and organizations including the American National Academy of Sciences (NAS), European Optical Society (EOS), The Optical Society (OSA), Ibero-American Network of Optics (RIAO), African Laser Atomic, Molecular, and Optical Sciences Network (LAM NETWORK), International Society on Optics Within Life Sciences (OWLS), and the International Society for Optics and Photonics (SPIE). The ICO general assembly will also take place during the same period.

We are looking forward to seeing you at ICO-24 in Tokyo during the summer of 2017.
