| 英文摘要 | 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. The semiconductor substrate preferably includes an active layer, a p-clad layer or reflective layer adjacent a first side of the active region, an n-clad layer or reflective layer adjacent a second side of the active layer, and an n-semiconductor layer adjacent the n-clad layer. 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 adjacent to the p-clad layer and proximate to the laser emission face, and an n-electrical contact adjacent to the n-clad layer or an n-semiconductor layer. The laser mode is defined by oxidized or ion-diffusion regions associated with the p-clad layer or n-clad layer of the laser. A conductive via through the substrate allows electrical connection with the p-side contact to be achieved from the n-side of the substrate. The optical head is used in a near-field optical system with an optical medium having a phase change layer. |
