Abstract: Optical components may be precisely positioned in three dimensions with respect to one another. A bonder which has the ability to precisely position the components in two dimensions can be utilized. The components may be equipped with contacts at different heights so that as the components come together in a third dimension, their relative positions can be sensed. This information may be fed back to the bonder to control the precise alignment in the third dimension.

Abstract: Optical components may be integrated into planar light circuits. For example, thin film filters may be integrated through trenches in planar light circuits to achieve demultiplexing of at least two multiplexed optical wavelengths. An optical waveguide may be interfaced with a laser or a light detector through a mode converter formed as a trench in the planar light circuit. The mode converter may have a curved surface to achieve mode conversion.

Abstract: Methods for fabricating merged magnetic heads, employing an inductive write head and a magnetoresistive (MR) read head which share portions of the overall magnetic structure, provide for accurate definition of the write track width and for improved alignment of the write gap and the read gap. The method includes accurately forming and defining the nonmagnetic write gap prior to fabricating the inductive write coil structure and subsequently formed higher topology elements. The methods provide for better control of the widths of the top pole member and the bottom pole member, thereby resulting in substantially equal widths for these pole members.

Abstract: A plurality of transducer elements are formed. For each of the plurality of transducer elements, an electrode of the transducer element is formed on a first side of a support layer. A piezoelectric element of the transducer element is formed on the first side of the support layer. An interconnect of the transducer element is formed in the support layer. The support layer is thinned to expose a second side of the support layer. The interconnects of the plurality of transducer elements extend between the first side and the second side of the support layer. The second side of the support layer is bonded to a flexible layer with an adhesive material. Conductive fillers are disposed in the adhesive material. The interconnects of the plurality of transducer elements are each electrically coupled via the conductive fillers to the corresponding interconnect extending through the flexible layer.

Abstract: Techniques and mechanisms to provide mechanical support for a micromachined piezoelectric transducer array. In an embodiment, a transducer array includes transducer elements each comprising a respective membrane portion and a respective supporting structure disposed on or around a periphery of that membrane portion. The transducer elements are initially formed on a sacrificial wafer, wherein supporting structures of the transducer elements facilitate subsequent removal of the sacrificial wafer and/or subsequent handling of the transducer elements. In another embodiment, a polymer layer is disposed on the transducer elements to provide for flexible support during such subsequent handling.

Abstract: An energy assisted magnetic recording (EAMR) disk drive comprises a suspension and a slider having a back side, a laser-facing surface, and an air-bearing surface (ABS) opposite the back side. The slider is mounted to the suspension on the back side. The disk drive further comprises an EAMR transducer coupled with the slider, a portion of the EAMR transducer residing in proximity to the ABS and on the laser-facing surface of the slider. The disk drive further comprises a laser coupled with the suspension and having a light emitting surface facing the laser-facing surface of the slider. The laser has an optic axis substantially parallel to the suspension. The laser provides energy substantially along the optic axis and is optically coupled with the EAMR transducer via free space. The EAMR transducer receives the energy from the laser and writes to the media using the energy.
