  • Patent number: 11588302
    Abstract: Exemplary methods and apparatus may provide optical gates and optical switches using such optical gates. Each optical gate may include a semiconductor optical amplifier that is placed in a substrate. The semiconductor optical amplifier may be coupled to input and output couplers to receive and selectively output optical signals into and out of the substrate.
    Type: Grant

  • Patent number: 10895684
    Abstract: A method, and apparatus provided thereby, includes providing a substrate and placing an integrated laser on the substrate. A first cladding layer surrounds the integrated laser and includes a laser optical coupler aligned with an output of the laser. The laser optical coupler includes silicon and the laser includes a III-V compound semiconductor. The output of the laser is spaced apart from the laser optical coupler by a gap of less than or equal to 500 nanometers. An optical waveguide is positioned on the first cladding layer and in optical communication with the laser optical coupler.

  • Patent number: 9899041
    Abstract: A write pole of a data writer may have at least one rotational milling operation conducted on a write pole blank followed by first and second static milling operations executed at different first and second angles with respect to an air bearing surface. The combination of rotational and static milling operations can form a write pole with body and tip regions defined by a continuous pole sidewall extending perpendicularly from the air bearing surface up to a body taper portion angled at approximately 14.5° with respect to the air bearing surface.

  • Patent number: 9734855
    Abstract: A data writer can have at least a write pole separated from a return pole by a non-magnetic lamination. The non-magnetic lamination may consist of first, second, and third non-magnetic materials that are each different and configured to provide a physical protrusion on an air bearing surface of less than 4 Angstroms.

  • Patent number: 9601136
    Abstract: A data storage device employing a data writer may configure the data writer with at least a write pole that is separated from a front shield on an air bearing surface. The front shield can be arranged to continuously extend from the air bearing surface a first throat height distal the write pole and a second throat height proximal the write pole with the first and second throat heights being different.

  • Publication number: 20140300995
    Abstract: A magnetic element can be configured as a data writer with at least a write pole contacting a yoke and having an air bearing surface. The write pole may be shaped to match a paddle surface of the yoke that extends perpendicular to the air bearing surface and facing parallel to the air bearing surface.

  • Patent number: 7233457
    Abstract: A perpendicular writer of the present invention comprises a main pole connected to two return poles and further includes one or more shorting shields thereby reducing erasure field on double layer perpendicular media. The perpendicular writer may include side shorting shields connecting the first and second return poles thereby modifying the crosstrack field gradient. Additionally, the perpendicular writer may include a top shorting shield modifying the downtrack gradient and may additionally include a bottom shorting shield for further reduction of erasure fields. The distance between the main pole and the shorting shields may be modified to customize the write field gradient.
