ABSTRACT:
A near-field optical system having one or more solid state lasers and an aerodynamically shaped slider which comprise a single integrated, monolithic device fabricated from the same base semiconductor material. The monolithic optical head can be quickly and easily attached to the read arm of an optical read/write device without requiring attachment of separate laser elements, and without micropositioning or use of optical microscopy for positioning the lasers. The optical head comprising a single semiconductor substrate including a first region which defines a slider having an air bearing surface, and at least one second, laser region which defines a diode laser, with the diode laser having an emission face which is substantially co-planar with the air bearing surface. A slider region of the semiconductor substrate includes an air bearing surface, adjacent the p-clad layer, which is aerodynamically structured and configured to define a slider. The integral lasers include a p-electrical contact and an n-electrical contact which are electrically accessible from one side of the laser, which allows the laser to be used directly with a drive circuit substrate.
