Abstract
Aspects described herein include a method of fabricating an optical component, the optical component, and a method of operating the optical component. A method includes electrically coupling a first laser channel and a second laser channel of a laser die to different electrical leads and testing (i) a first optical coupling of the first laser channel and a second optical coupling of the second laser channel or (ii) a first spectral performance of the first laser channel and a second spectral performance of the second laser channel. The method also includes optically aligning an optical fiber with the first laser channel and designating the second laser channel as a heater element for the first laser channel based at least in part on (i) the first optical coupling being greater than the second optical coupling or (ii) the first spectral performance relative to the second spectral performance.
