The Institute for-Cross Disciplinary Physics and Complex Systems, IFISC, and The Optical Society of America, OSA, organized between 6 and july 10, the First Modern Optics Days. A group of 20 students in the field of Physics and Engineering of the Universitat de les Illes Balears attended the IFISC-OSA conferences that introduced them to the field of XXI Century Optics, and provide them information on the issues being investigated by the International ScientificCommunity. These days were also useful to facilitate communication and debate among participants and students on that discipline.
