This patent describes a optical modulation apparatus, it comprises means for providing a first laser beam centered at a wavelength [lambda]: means for providing a second laser beam centered at a wavelength [lambda] + [Delta][lambda]; a polarization preserving optical fiber comprising two polarization preserving axes, including a main axis and an orthogonal axis extending from an optical entrance to an optical exit; a means for coupling a single polarization of the first laser beam into the entrance of the optical fiber along the main axis; a means for coupling a single polarization of the second laser beam into the entrance of the optical fiber; a means for coupling an output beam from the optical exit of the optical fiber; and a means for selecting a single polarization of the output beam from the optical fiber.
