Abstract
A method of optimally aligning an optical fiber to a semiconductor laser diode, aligns the optical fiber to the semiconductor laser diode, attaches a solder preform onto the optical fiber, and applies a low power localized heat to the solder preform in order to thermally shift the optical fiber downward into an optimized alignment. The method may further include intermediate alignment steps including application of a preload force on the fiber in a direction compensatory to the direction of misalignment, and activation of a high power localized heat to reflow the solder so that the fiber may be moved to the optimized position. These steps may be performed multiple times until a substantially optimized coupling is achieved.
