Abstract
According to an aspect of an embodiment, operations may include receiving a light wave and generating a pumping wave by performing polarization modulation on the light wave based on a bit stream. The pumping wave may include a first polarization component having a first polarization and a second polarization component having a second polarization and having a same wavelength as the first polarization component. The operations may also include emitting the pumping wave in an optical medium such that the pumping wave amplifies an optical signal propagating within the optical medium.
