Method and apparatus for aligning a laser to a waveguide

摘要

An apparatus includes a slider structure having a waveguide and a cavity configured to align a laser to the waveguide. The cavity includes a plurality of solder bumps on a bottom of the cavity configured to electrically and thermally couple the laser to the slider. At least one mechanical stopper is disposed in the cavity to facilitate vertical alignment between an output of the laser and an input of the waveguide. At least one solder bump is disposed on the mechanical stopper to facilitate lateral alignment between the output of the laser and the input of the waveguide in response to a reflow of the solder bumps.
