Institut de Ciències Fotòniques

 L'Institut de Ciències Fotòniques té com a objectius la recerca, la docència i l'incentiu del sector industrial en l'àmbit de les ciències de la llum i de totes les disciplines en les quals la fotònica tingui incidència, com ara les nanotecnologies òptiques, les tecnologies de la informació, les biotecnologies, les ciències de la salut i de la vida, les tecnologies de la informació quàntica i els sistemes làser. Referent únic a Europa per les seves característiques, l'ICFO es va crear com a fundació privada el març de 2002, constituïda inicialment per la UPC i el Departament d'Universitats, Recerca i Societat de la Informació (DURSI) de la Generalitat de Catalunya.
