We present a new optoelectronic architecture intended for chaotic optical intensity generation. The principle relies on an electro-optic non-linear delay dynamics, which non linearity is performed by a 4-waves integrated optics interferometer involving 2 independent electro-optic modulation inputs. The setup allows both to have an ultra-fast dynamics up to several GHz frequencies, and potentially high dimensional chaos intended for encryption of optical data at the physical layer. We have built a mathematical model of the system and analyzed a number of its possible solutions: stable steady states, periodic and chaotic regimes. The experimental observations allowed to validate the dynamical model, through good qualitative agreements with the numerical simulations.
