Abstract
An apparatus comprising a comb generator and multiple modulators is described. In one embodiment, the comb generator generates a multi-wavelength comb of optical frequencies. Each of the modulators receives the comb on one input as well as an input data signal on another input. Each of the modulators modulates the comb with its input data signal, thereby creating a modulated comb signal having duplicate signal sidebands on each spectral line of the comb. Each modulator outputs the modulated comb signal on the output.
