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.

An apparatus comprising:
- a comb generator to generate a multi-wavelength comb of optical frequencies;
- and
- a plurality of modulators coupled to receive the comb, each of the plurality of modulators having an input to receive an input data signal and an output, each of the plurality of modulators to modulate the comb with its input data signal creating a modulated comb signal having duplicate signal sidebands on each spectral line of the comb and to output the modulated comb signal on the output.
A method comprising:
- generating a multi-wavelength comb of optical frequencies;
- simultaneously modulating the comb with a plurality of modulators with a set of modulating signals received as input data signals by the plurality of modulators to create a modulated comb signal having duplicate signal sidebands on each spectral line of the comb;
- and
- outputting the modulated comb signal on an output of each of the plurality of modulators.
