ICO is Affiliated Member of the International Science Council (ISC)


At age 58, ICO is moving ahead to better and more visibly fulfill its mission as "the place where the world of Optics meets": it was just elected an International Scientific Associate at the ICSU General Assembly in October 2005. The whole field of optics is thereby improving its recognition as a discipline, in many ways connected to all other disciplines within science and technology. Let us explain why and how this is so, at the same time reviewing what ICSU was, and exactly what move ICO just made in the ICSU family.

ICSU, known as the International Council for Science, retained the acronym of its original name, the International Council of Scientific Unions. An independent international organization, it represented all disciplines, promotes their interaction in interdisciplinary actions, and fosters scientific research through its links with other international bodies, in particular in relation with global challenges that mankind is facing such as sustainable development, earth observation, energy, and food security. Since 2018 ICSU and the ISSC (the international Social Sciences Council) merged in the ISC (International Science Council) and ICO became Scientific Associate of the nre organization.

The concept of national membership in ICSU extended to many members of the ICSU family: this is really why, since it was first created in 1947, ICO's membership was primarily based on national membership, the Territorial Committee Members in the current ICO terminology. In addition, ICSU has members that represent scientific disciplines at an international level. These were the ICSU International Union Members. One of the 25 or so Union Members was the International Union of Pure and Applied Physics, IUPAP. In the ICSU construct, IUPAP itself had national members and 'Commissions' representing the various branches of Physics. Among the commissions, a few enjoy the status of an independent organization and have their own membership and budget: these are the IUPAP 'Affiliated Commission', a status that ICO has shared since its creation. This structure has been preserved in the new ISC configuration.

An important step in the recent history of ICO, though, is the creation, in 1999, of a new category of membership, the 'International Society Members', to recognize the fact that most international scientific conferences nowadays, as opposed to the situation in 1947, are organized by large societies that have individual members and that are explicitly active internationally. As of today, ICO has fifty Territorial Committee Members and six International Society Members. With this structure, ICO has a fair claim at representing the whole field of Optics on an international scale.

By moving to the status of an ISC 'Scientific Associate', the desire of ICO is to make it clear that with the continuous development of science and technology in research and industry, the relation between Optics and Physics has become more complex. Optics still has its roots deeply in Physics and this will remain so - let it be enough to mention at this point the 2005 Nobel Prize in Physics, which was awarded to Roy J. Glauber, John L. Hall, and Theodor W. Hänsch for outstanding upstream work in optics, with practical implications. Indeed, in parallel to being raised to the status of an ISC Scientific Associate, ICO keeps its status as an IUPAP Affiliated Commission. Yet, large branches of Optics developed where scientists and engineers do not consider them selves physicists and are not considered as such by physicists. This applies, for example, to most work in optical systems and in optical telecommunications. Optics courses and research activities at many universities are more and more being promoted to full fledged departments. The recognition of optics professions and degrees by accredited institutions is a significant issue in various countries. This all boils down to one conclusion: Optics is more and more perceived as a scientific discipline of its own. Its recognition as an ISC Scientific Associate is one further step in that direction.

Within the ISC constellation, ICO will be acting at par with other international societies and unions, and will participate in the appropriate ISC activities, being able to liaise between the Optics community and ISC by bringing up and promoting opportunities for actions involving optics that bear a global dimension both geographically and topically. This includes, directly in line with a clear ICO priority item, actions for the support of science and technology in regions of the world that deserve special measures, such as its long standing collaboration with the Abdus Salam International Centre for Theoretical Physics at Trieste.

Optics is relevant to most ISC priorities on the global role of science and technology and, as a global organization promotes the dissemination and advancement of scientific and technical knowledge in the broad fields of optics: make contacts, provide expertise, offer a neutral international character, etc. More importantly, it is one step forward for the recognition of the importance of Optics for Science and for Society in the 21st century. ICO will strive to make best use of this opportunity and calls to its members and the many parts of the Optics community that they represent to join it and contribute new initiatives.
