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.
