Coupling multi-channel laser to multicore fiber

Abstract:

Aspects described herein include a method comprising arranging a laser die on a substrate. The laser die has multiple channels that are arranged with a first planar arrangement proximate to a facet of the laser die. The method further comprises aligning a single lens to the facet, and aligning a multicore optical fiber to the laser die through the single lens. The multicore optical fiber has a plurality of optical cores that are arranged with a second planar arrangement. Aligning the multicore optical fiber to the laser die comprises rotationally aligning the multicore optical fiber to align the second planar arrangement with the first planar arrangement.
