Latest results on electro-optic chaos communications will be reported. The results were obtained in the recently achieved EC project PICASSO, in the frame of a close collaboration with the IFISC (initiated during a previous EC project OCCULT, 2001-2004). The specific experimental architecture which allowed the achievement of state of the art in chaos communication, is based on a novel electro-optic phase delay dynamics, with a temporally nonlocal nonlinearity. The basic principle of operation of this delay dynamics inspired by the Ikeda one, will be described and discussed. Dynamical features will be reported, and compared to previously observed ones with dynamics on electro-optic intensity chaos generator. Finally we will report on the record chaos communication results recently obtained at bit rate up to 10Gb/s, both in back-to-back and long distance transmission experiments. Also field experiments have been performed, both in the local fiber network of the city in Besancon, France, and the one in Athens, Greece. Security issues will be finally addressed, proposing dedicated hardware configurations which should offer in the future strongly enhanced security levels. Other perspectives will be proposed for this phase chaos architecture, whether for mutual coupling chaos synchronization issues, or optical liquid state machines.
