Abstract
An integrated optical device including at least one hybrid optical junction with two input paths and two output paths, for transmitting light energy from the input to the output paths as a function of phase difference between the inputs. The junction includes a Y-shaped node formed by three monomodal optical wave-guides situated in a refractive medium with a lower refractive index than that of the three wave-guides.
