Method and system for optically coupling a laser with a transducer in an energy assisted magnetic recording disk drive

A method for providing an energy assisted magnetic recording (EAMR) head including a slider, an EAMR transducer coupled with the slider and a laser coupled with the slider, the method comprising:

• passively aligning the laser with the slider, the laser including a main emitter and at least one alignment emitter, the slider including at least one alignment waveguide, at least one output device, and an air-bearing surface (ABS), the EAMR transducer including a waveguide, the step of passively aligning the laser with the slider including passively aligning the at least one alignment waveguide with the at least one alignment emitter;
• and
• actively aligning the laser with the slider using the at least one alignment emitter, the at least one alignment waveguide, and the at least one output device.

A method for providing a plurality of energy assisted magnetic recording (EAMR) heads including a plurality of sliders, a plurality of EAMR transducers coupled with the plurality of sliders, and a plurality of main emitters coupled with the plurality of sliders, the plurality of sliders residing on a slider bar, the method comprising:
