ABSTRACT:
The modulator comprises an integrated optical switch (6) receiving at an input a linearly-polarized optical carrier and transferring same to a first or a second output (P3, P4), according to the logic values of the bits of a modulating binary data signal. The radiations outgoing from the switch are sent to a polarizing beam splitter (13) with their original polarization or with a polarization rotated by 90.degree. depending on the switch output (P3, P4) from which they come. A signal with the original polarization or with the polarization rotated by 90.degree. is present at the splitter output, depending on the logic values of the bits of the modulating signal.
