As of the end of 2011, POPsud has 183 members, including:
- 112 companies
- 30 laboratories
- 14 higher education organisations
- 27 partners
An even spread throughout the territory
Of the 183 members, 81 % are located in the Provence Alpes Côte d'Azur and Languedoc-Roussillon Regions. The fact that POPSud is also active in other regions reflects by the strong power of attraction of the POPsud photonics cluster, in particular for companies in Rhône-Alpes and Ile-de-France.
