Laser Module for Optical Data Communication System

A laser module, comprising:

• a planar lightwave circuit including both a laser source and an optical marshalling module, the laser source including a plurality of lasers, wherein each laser of the plurality of lasers is configured to generate a different wavelength of continuous wave light, the optical marshalling module having a plurality of optical output ports, the optical marshalling module configured to convey a portion of the continuous wave light generated by each laser of the plurality of lasers to each of the plurality of optical output ports, such that all wavelengths of continuous wave light generated by the plurality of lasers are conveyed to each of the plurality of optical output ports of the optical marshalling module;
• and
• an optical amplifying module configured to amplify light conveyed through each of the plurality of optical output ports of the optical marshalling module.

A method for manufacturing a planar lightwave circuit, comprising:

• forming a plurality of lasers within the planar lightwave circuit, wherein each of the plurality of lasers is configured to generate continuous wave light having a respective wavelength that is different than wavelengths of continuous wave light generated by others of the plurality of lasers;
• and
• forming an optical marshalling module within the same planar lightwave circuit as the laser source, wherein the optical marshalling module is formed to convey a portion of the continuous wave light output by each of the plurality of lasers to each of a plurality of optical output ports of the optical marshalling module, such that all wavelengths of continuous wave light generated by the plurality of lasers are conveyed to each of the plurality of optical output ports of the optical marshalling module.
