Abstract
A heat-assisted magnetic recording head includes a slider body having a waveguide that delivers light to a near-field transducer. The waveguide is optically coupled to an input coupler a of the slider body that receives the light. A laser diode is mounted on or in the slider body. The laser diode has an integral exit facet proximate the input coupler. The exit facet has a curved profile that modifies a shape of the light emitted from the exit facet into the input coupler.
