A method and system for providing an energy assisted magnetic recording (EAMR) disk drive are described. The EAMR disk drive includes a media, a slider having a trailing face, at least one EAMR head on the slider, and at least one vertical surface emitting laser (VCSEL). The VCSEL(s) includes a plurality of quantum wells and an extended resonance cavity. The VCSEL(s) provides energy to the EAMR disk drive. The extended resonance cavity extends into the slider and is oriented substantially perpendicular to the trailing face of the slider. The EAMR head(s) include grating(s), waveguide(s), a write pole, and coil(s) for energizing the write pole. At least a portion of the grating(s) reside in the extended resonance cavity and couple energy from the VCSEL to the waveguide(s). The waveguide(s) direct the energy from the grating(s) toward the media.
