An optoelectronic integrated semiconductor device including a separator of the polarizations TE and TM, this separator comprising two parallel and monomode optical guides G1 and G2, one of which receives at the input a luminous signal, and comprising means for carrying out the separation of this signal and its two components TE and TM, one of which TE is transported to the output through one of the guides and the other component TM is transported to the output through the other guide, characterized in that: the guides are formed by at least a heterostructure S/C1 and by two parallel erected guiding ribbons R at the surface, and the means for carrying out the separation of the components TE and TM consist of a matallic layer extending between the guiding ribbons at the surface of the structure over a length D, whose value is connected with the coupling length of the component TE by the relation D=Lc(TE), the parameters of the physical quantities of the device being chosen so that the relation Lc(TE)=2Lc(TM), is satisfied
