Abstract
An apparatus includes a transducer assembly including a waveguide and a grating structured to couple electromagnetic radiation into the waveguide; and a body including an extended cavity vertical cavity surface emitting laser diode, and having an air bearing surface, wherein the transducer assembly is positioned adjacent to the body and the laser diode directs electromagnetic radiation onto the grating. A method of making the apparatus is also included.
