Abstract
Briefly, in accordance with one or more embodiments, a band of signal carriers is divided into a first band of carriers and a second band of carriers. The carriers in the first band comprise shorter wavelength carriers, and carriers in the second band comprise longer wavelength carriers. Each of the optical sources in the first and second bands of carriers are modulated with an input signal and coupled together via a polarization maintaining coupler. These signals are then combined via a polarization beam combiner wherein the first band has a polarization state that is orthogonal, or nearly orthogonal, to a polarization of the second state.
