Abstract
Aspects described herein include a method of fabricating an optical component. The method comprises electrically coupling different laser channels of a laser die to different electrical leads, testing a respective optical coupling of each of the different laser channels, optically aligning an optical fiber with a first laser channel of the different laser channels having the greatest optical coupling, and designating a second laser channel of the different laser channels as a heater element for the first laser channel.
