Abstract
Optical devices and methods of manufacture are presented in which a fiber array unit is utilized to arrange optical fibers so that, once the fiber array unit is attached to an optical device such as a first optical package, the optical fibers are better aligned with edge couplers within the first optical package after the edge couplers have been warped out of a straight alignment.
Claims20
A method of manufacturing an optical device, the method comprising:
- receiving a fiber array unit, wherein after the receiving optical fibers extend through the fiber array unit, wherein the optical fibers are arranged in a plurality of groupings, each grouping of the plurality of groupings being offset from adjacent groupings of the plurality of groupings by a first distance, the first distance being less than a diameter of one of the optical fibers;
- and
- attaching the fiber array unit to an optical device.
A method of manufacturing an optical device, the method comprising:
- bonding a first optical package to an interposer substrate, wherein the bonding warps a line of edge couplers within the first optical package;
- and
- attaching a fiber array unit to a first side of the first optical package, the fiber array unit comprising:
- a first group of optical fibers;
- and
- a second group of optical fibers, the second group of optical fibers being offset from the first group of optical fibers by a distance of less than about 2 μm.
