High-speed modulator of the polarization of an optical carrier.

摘要

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 DEG depending on the switch output (P3, P4) from which they come. A signal with the original polarization or with the polarization rotated by 90 DEG is present at the splitter output, depending on the logic values of the bits of the modulating signal.
