Energy-efficient optical source
An optical source includes a set of N light sources that provide a corresponding set of N optical signals having N carrier wavelengths. These optical signals are combined into a seed optical signal and transported to a substrate using an optical fiber. This substrate includes a set of K optical amplifiers that amplify the seed optical signal and provide a set of M output optical signals on a corresponding set of M output optical waveguides (where M is less than K). In this way, a total power of the set of M output optical signals may be significantly larger than that of the seed optical signal, thereby ensuring that a majority of a power efficiency of the optical source is associated with power efficiencies of the set of K optical amplifiers instead of power efficiencies of the set of N light sources.
