Tunable Micro-Lens Array

View page
US Patent:
6999238, Feb 14, 2006
Filed:
Dec 1, 2003
Appl. No.:
10/725840
Inventors:
Alexei Glebov - San Mateo CA, US
Lidu Huang - Danville CA, US
Kishio Yokouchi - San Jose CA, US
Assignee:
Fujitsu Limited - Kawasaki
International Classification:
G02B 26/00
G02B 27/10
US Classification:
359619, 359620, 359290
Abstract:
A tunable micro-lens and micro-lens array for use in optical communications are disclosed. The micro-lens uses thermo optical material and a temperature controller to adjust the temperature and, hence, the index of refraction of the thermo optical material. In one embodiment, a single temperature controller is used to maintain an array of micro-lenses at a desired temperature. In an alternate embodiment, the individual lenses in an array are separately tunable. The invention may be used with either 2D or 3D lenses, and is well suited for use with existing planar lightwave circuit (PLC) technology.

One-By-N Optical Switch

View page
US Patent:
7171083, Jan 30, 2007
Filed:
Feb 4, 2004
Appl. No.:
10/771562
Inventors:
Kishio Yokouchi - San Jose CA, US
Lidu Huang - Danville CA, US
Shigenori Aoki - Sunnyvale CA, US
Assignee:
Fujitsu Limited - Kawasaki
International Classification:
G02B 6/35
G02F 1/295
US Classification:
385 41, 385 22, 385 9
Abstract:
An all-optical one-by-N optical switch is provided that has fewer components, is easier to control and has fewer optical losses that prior art one-by-N optical switches. An optical switch of the present invention includes an active deflection element formed from an electro-optical material to deflect an optical input from a single input to a selected one of N outputs. In one embodiment of the present invention, a single active deflection element at the input deflects an optical signal across a waveguide that commonly connects the N outputs. The N optical outputs include passive optical elements that are aligned with the deflected optical signal to accept a signal and provide it to a selected optical output. The optical switch can either be monolithic, where the optical material are all electro-optical materials, or can be hybrid, having separately formed components, such as the common waveguide, adhered to the substrate on which the optical switch is formed.

Mar 15, 2005
Appl. No.:
11/080042
Inventors:
Lidu Huang - Danville CA, US
Kishio Yokouchi - Tokyo, JP
Assignee:
Fujitsu Ltd. - Kawasaki
International Classification:
G02B 6/12
G02B 6/124
G02B 6/32
G02B 6/34
US Classification:
385 14, 385 33, 385 37, 385 50, 385129
Abstract:
Optical backplanes providing integrated optical couplers to external optical fibers are disclosed, along with methods for making the same. An exemplary optical backplane has a first cladding layer disposed over the top surface of a substrate, and at least a first core body disposed over the first cladding layer, with the first core body having a first end and a second end. A material layer is disposed above the first cladding layer and the first end of the first core body, with the material layer having a top surface and a bottom surface. A focusing element is formed at the top surface of the material layer, with the focusing element being located above the first end of the first core body.

US Patent:
7283220, Oct 16, 2007
Filed:
Mar 24, 2004
Appl. No.:
10/808665
Inventors:
Lidu Huang - Danville CA, US
Alexei Glebov - San Mateo CA, US
Shigenori Aoki - Sunnyvale CA, US
Michael G. Lee - San Jose CA, US
Kishio Yokouchi - San Jose CA, US
Assignee:
Fujitsu Limited - Kanagawa
International Classification:
G01N 21/41
US Classification:
356128
Abstract:
Methods and apparatuses for measuring the optical properties of solids, gels, and liquids are disclosed. The apparatuses may be constructed on miniature substrates using conventional semiconductor wafer and packaging processes. The substrates may be mass-produced on wafers, which are then diced to provide individual miniature substrates. High measurement precision, low-manufacturing costs, and other benefits are provided by the present inventions.

Disk Drive With An Actuator Latch Having Fixed, Latching, And Latch Arm Portions Being A Single Component

View page
US Patent:
7633721, Dec 15, 2009
Filed:
Feb 1, 2006
Appl. No.:
11/345445
Inventors:
Aaron D. Little - Campbell CA, US
Lidu Huang - Danville CA, US
Assignee:
Western Digital Technologies, Inc. - Lake Forest CA
International Classification:
G11B 5/54
G11B 21/22
US Classification:
3602562
Abstract:
A disk drive includes a disk drive base and an actuator that is rotatably coupled to the disk drive base. The actuator has an axis of rotation. The disk drive further includes a latch. The latch includes a fixed portion that is firmly coupled to the disk drive base, and a latching portion. The latch further includes a latch arm portion connecting the latching portion to the fixed portion. The latch arm portion includes a hinge region. The latch arm portion is thinner in a direction normal to the axis of rotation in the hinge region than the latch arm portion is outside of the hinge region. The latch arm portion, the latching portion, and the fixed portion are a single component having material continuity rather than an assembly of sub-components.

Disk Drive Including An Actuator Latch With A Pivot Ball In A Latch Post Opening And Between A Vcm Top Plate And The Latch

US Patent:
7660075, Feb 9, 2010
Filed:
Feb 1, 2006
Appl. No.:
11/345354
Inventors:
Jianren Lin - San Jose CA, US
Lidu Huang - Danville CA, US
Nils E. Larson - San Jose CA, US
Assignee:
Western Digital Technologies, Inc. - Lake Forest CA
International Classification:
G11B 5/54
G11B 21/16
E05D 7/10
E05D 7/12
US Classification:
3602562, 16258
Abstract:
A disk drive includes a housing including a support post extending from the housing. The support post defines a post axis. The disk drive further includes an actuator rotatably coupled to the housing. The disk drive further includes a VCM top plate physically coupled to the housing and comprising a ferromagnetic metal. The disk drive further includes a VCM magnet magnetically coupled to the VCM top plate. The disk drive further includes an actuator latch contactable with the actuator. The latch includes a post opening. The latch is pivotably mounted about the support post with the support post disposed in the post opening. The disk drive further includes a pivot ball disposed in the post opening and partially protruding from the latch between the VCM top plate and the latch along the post axis.

Disk Drive With Translatable Ramp

View page
US Patent:
7672083, Mar 2, 2010
Filed:
Feb 13, 2006
Appl. No.:
11/352534
Inventors:
William Wei Yi Yu - Anne Arbor MI, US
Lidu Huang - Danville CA, US
Perry E. Hall - Hollister CA, US
Scott E. Watson - San Jose CA, US
Kenneth Allen - Felton CA, US
Lawrence H. Lo - Cupertino CA, US
David K. Myers - Campbell CA, US
Assignee:
Western Digital Technologies, Inc. - Lake Forest CA
International Classification:
G11B 5/54
US Classification:
3602544, 3602545, 3602549
Abstract:
A disk drive having a translatable ramp is disclosed. The disk drive includes a head gimbal assembly having a proximate end that is attached to an actuator, and a distal end that includes a lift tab. The ramp includes a lift tab supporting surface located as close to a pivot axis of the actuator as is the lift tab. The ramp also includes a ramp guiding surface that is in contact with a mating surface of the disk drive base. A fastener selectively allows or prevents relative translation between the ramp and the disk drive base. The aforementioned contact constrains the relative translation so that the relative translation changes the distance between the lift tab supporting surface and the disk axis of rotation more than the relative translation changes the distance between the lift tab supporting surface and the actuator pivot axis.
