摘要： A near-field optical apparatus 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.

摘要： A hybrid magnetic-optical head apparatus wherein one or more solid state lasers, magnetic field biasing elements, magnetic sensing elements, and an aerodynamically shaped slider comprise a single integrated, monolithic device fabricated from the same base semiconductor material into an optical head. 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 and magnetic elements, and without micropositioning or use of optical microscopy for positioning the lasers or magnetic elements. The hybrid magnetic-optical head apparatus includes a magnetic-optical function region having a semiconductor laser and at least one magnetic element. Preferably, the magnetic-optical function region of the substrate includes a magnetic field biasing element associated with the semiconductor laser, as well as a magnetic sensing element. The slider portion of the magnetic optical head preferably includes an aerodynamically shaped air cavity as well as an air bearing surface, with the emission face of the laser preferably is substantially co-planar with the air bearing surface. The magneticoptical function region may be configured for magnetically assisted thermal recording wherein writing is carried out primarily by laser power modulation to selectively heat portions of a medium, together with assistance of an applied magnetic field to establish a preferred direction of magnetization pattern in the medium. The magnetic-optical function region may alternatively be configured for thermally assisted magnetic writing wherein writing is carried out primarily by modulation of magnetic field, together with assistance of a laser which heats the medium to reduce the medium coercivity and thereby assist in the magnetic recording.

摘要： The polarization instability inherent in laterally-oxidized VCSELs may be mitigated by employing an appropriately-shaped device aperture, a misoriented substrate, one or more cavities or employing the shaped device aperture together with a misoriented substrate and/or cavities. The laterally-oxidized VCSELs are able to operate in a single polarization mode throughout the entire light output power versus intensity curve. Combining the use of misoriented substrates with a device design that has an asymmetric aperture that reinforces the polarization mode favored by the substrate further improves polarization selectivity. Other device designs, however, can also be combined with substrate misorientation to strengthen polarization selectivity.

摘要： A near field optical apparatus comprising a conductive sheet or plane having an aperture therein with the conductive plane including at least one protrusion which extends into the aperture. The location, structure and configuration of the protrusion or protrusions can be controlled to provide desired near field localization of optical power output associated with the aperture. Preferably, the location, structure and configuration of the protrusion are tailored to maximize near field localization at generally the center of the aperture. The aperture preferably has a perimeter dimension which is substantially resonant with the output wavelength of the light source, or is otherwise able to support a standing wave of significant amplitude. The apparatus may be embodied in a vertical cavity surface emitting layer or VCSEL having enhanced nearfield brightness by providing a conductive layer on the laser emission facet, with, a protrusion of the conductive layer extending into an aperture in the emission facet. The aperture in the emission facet preferably has dimensions smaller than the guide mode of the laser, and the aperture preferably defines different regions of reflectivity under the emission facet. The depth of the aperture can be etched to provide a particular target loss, and results in higher optical power extraction from the emission facet.

摘要： A monitoring system for detection of defects in an optical fiber coating during production of the fiber has first and second beam generating means which produce planar coherent beams which cross each other at the fiber passing through the system creating one or more diffraction patterns. A first plurality of photodetectors are mounted in a mount, the front face of which is impinged by the planar diffraction pattern, and a second plurality of photodetectors is similarly mounted in position below the impinging pattern. A defect in the fiber coating, regardless of shape or orientation, will cause the pattern or patterns to be tilted or shifted upward, downward, or planarly tilted to impinge one or more of the photodiodes which, as a result, generates a signal which is applied to a comparator and control circuit.

摘要： This invention provides a method of producing a series of substantially uniform spot welds between two metal parts using a servomotor driven movable electrode and an axially opposing fixed electrode. Target values for electrode displacement in producing a weld indentation and electrode squeeze force are determined for the electrodes and workpieces. During welding operations electrode displacement and electrode force measurements are continually taken and compared with the displacement and force target values. While the measured values are within a tolerance range of the target values, welding is continued using the preset parameters. When either or both of the measured electrode displacement or force value falls outside the target range the total welding current is adjusted in small increments to correct the displacement and/or force values and, thereafter, welding is continued using the new total welding current.
