Abstract
A substrate includes a first area in which a laser array chip is disposed. The substrate includes a second area in which a planar lightwave circuit is disposed. The second area is elevated relative to the first area. A trench is formed in the substrate between the first area and the second area. The substrate includes a third area in which an optical fiber alignment device is disposed. The third area is located next to and at a lower elevation than the second area within the substrate. The planar lightwave circuit has optical inputs facing toward and aligned with respective optical outputs of the laser array chip. The planar lightwave circuit has optical outputs facing toward the third area. The optical fiber alignment device is configured to receive optical fibers such that optical cores of the optical fibers respectively align with the optical outputs of the planar lightwave circuit.
