Classification: CPC G  H | IPC G

Claim 0:
1. A method for manufacturing a multi-wavelength source, comprising:
forming a substrate to include a first area for receiving a chip;
forming the substrate to include a second area elevated relative to the first area;
forming the substrate to include a trench between the first area and the second area, the trench having a bottom at a lower elevation within the substrate than the first area;
forming the substrate including a third area next to the second area, the third area having a lower elevation within the substrate than the second area;
disposing a laser array chip in the first area, such that optical outputs of the laser array chip face toward the second area;
disposing a planar lightwave circuit in the second area, such that optical inputs of the planar lightwave circuit face toward and align with respective optical outputs of the laser array chip, and such that optical outputs of the planar lightwave circuit face toward the third area; and
disposing an optical fiber alignment device in the third area, the optical fiber alignment device configured to receive a number of optical fibers such that optical cores of the number of optical fibers respectively align with the optical outputs of the planar lightwave circuit; wherein the trench is formed to extend along a full length of a side of the laser array chip that faces toward the planar lightwave circuit.
