Patent number: 6330253Abstract: The present invention provides an apparatus for passively stabilizing the tuning element in tunable lasers. Lasers stabilized using the passive stabilization of the tuning element exhibit reduced mode hop and increased wavelength stability during temperature variations of the laser or surrounding environment. The stabilization makes the laser suitable for a broad range of applications including optical signal generators and optical multimeters.Type: GrantFiled: September 10, 1999Date of Patent: December 11, 2001Assignee: New Focus, Inc.Inventors: Alexander V. Tuganov, David F. Arnone, Bruce A. Moore, Emmerich Mueller

Patent number: 6266196Abstract: A multi-position optic mount is disclosed which provides for automatic movement of an optic element between an engaged position, in which the optic element intersects an optical path, and a disengaged position, in which the optic element avoids an optical path. The optic mount may be used for a broad range of optical elements including: lenses, filters, etalons, gratings, retroreflectors, wave guides, fiber optics, lasers, photo-detectors, etc. A unique activation capability is provided in which an active actuator and passive actuator are utilized to move the mount between the engaged and disengaged positions.Type: GrantFiled: November 19, 1999Date of Patent: July 24, 2001Assignee: New Focus, Inc.Inventors: Khiem Do, David F.

Patent number: 6174102Abstract: A modular approach to the design of motion modules, e.g., positioning elements, is provided. Thus, a single positioning element can be integrated into a number of multi-axis configurations through combination with other basic positioning elements all of which share a modular interlocking feature. In an embodiment of the invention a motion module is disclosed which includes a base and a mobile stage. The base includes an exterior surface and a first interconnector located on the exterior surface. The mobile stage includes an exterior surface and a second interconnector. The mobile stage is positionable with respect to the base. The second interconnector is located on the exterior surface of the mobile stage. The first and the second interconnector are mutually engagable in releasable frictional engagement with second and first interconnectors of other motion modules for stackable interconnection therebetween.Type: GrantFiled: January 26, 1998Date of Patent: January 16, 2001Assignee: New Focus, Inc.Inventors: Khiem Ba Do, David F.

Patent number: 5995521Abstract: Disclosed are both a housing and an assembly for a tunable external cavity laser. The housing includes: a base section, a motion section, and an actuator. The base section includes a proximal and distal portion, and the laser and the dispersive element mounted at respectively the proximal and distal portions such that energy emanating from the laser strikes the dispersive element leaving the dispersive element as a second beam at an angle with respect to the first beam which depends on wavelength. The motion section includes a proximal and a distal portion and a torsional member positioned at the proximal portion and the reflector positioned at the distal portion to reflect the second beam to the laser via the dispersive element, and the motion section supported by the base about the torsional member.Type: GrantFiled: May 14, 1998Date of Patent: November 30, 1999Assignee: New Focus, Inc.Inventors: Bruce A. Moore, David F. Arnone, Robert L. MacDonald, Francis S. Luecke

Patent number: 5953164Abstract: An improved optical mounting apparatus permits a single kinematically adjustable surface to be presented in either a horizontal or vertical orientation with respect to a support. A three point fastening system allows cylindrical optical elements of various sizes to be fastened to the kinematically adjustable surface in a horizontal orientation. The three point fastening system is removable so that when the kinematically adjustable surface is placed in a horizontal orientation transparent optical elements such as prisms can be fastened to the surface with an unobstructed optical path for a full 360.degree. around the mounting surface. The apparatus for mounting optical elements comprises a support, base plate, a pivot member, two adjustable projections, a stage plate, and at least three removable fasteners. The base plate includes first and third opposing faces and a second face at right angles to the first and third faces.Type: GrantFiled: September 29, 1998Date of Patent: September 14, 1999Assignee: New Focus, Inc.Inventors: David F. Arnone, Michael Brownell, Sherwin D. Cabatic, Khiem Ba Do

Patent number: 5936785Abstract: An optic mount for holding an optic element in a light path is provided. The optic mount includes a base and a holder. A base and a holder are pivotally connected. The holder includes an optic bore. The optic bore is dimensioned to contain an optical element. Arcuate movement of the holder with respect to the base allows an optic element to be moved from a first position, in which the light path passes through the optic bore to a second position in which the optic bore avoids the light path. In another embodiment of the invention, a modular configuration of optic mounts for holding a plurality of optic elements in a light path is provided. The modular configuration includes at least two base and holder pairs. Each base and holder are pivotally connected. Each holder includes an optic bore. The optic bores of both holders are dimensioned to hold an optical element. The first and second bases are aligned by complementary interlocking elements on the opposing faces of each of the base units.Type: GrantFiled: September 14, 1998Date of Patent: August 10, 1999Assignee: New Focus, Inc.Inventors: Khiem Ba Do, David F. Arnone

Patent number: 5933353Abstract: In an embodiment, the controller for machining parts on a work piece positioned on a numerically controllable (NC) machine includes a memory, a display and a plurality of layout processes. A job comprising multiple parts in various quantities is displayed textually as a job list of parts and quantities. The job is also displayed graphically in a scaled layout. In the scaled layout part icons corresponding to each of the parts on the job list are superimposed on a work piece icon in an arrangement corresponding to a physical part layout. Layout processes handle the location of the machine instruction records which correspond to the parts selected for the job. These processes also determine the dimension and scaling of each part icon on the basis of the machine code records for the chosen parts. The processes also handle the scaling of the work piece icon and parts icon on the display in an arrangement corresponding to an actual physical layout for the job.Type: GrantFiled: September 16, 1997Date of Patent: August 3, 1999Assignee: New Focus, Inc.Inventors: Rosemary O. Abriam, David F. Arnone

Patent number: 5400674Abstract: A precision component mounting and positioning apparatus comprises a frame member and a stage member suspended in the frame member. The frame member is adapted to be mounted on a support surface, and the stage member is adapted to receive a precision component, typically a precision optical component such as an optical fiber or waveguide. The stage member can be positionally adjusted relative to the frame member in five degrees of freedom. Three axially oriented actuators are grounded in the frame member to provide for selectively rotating the stage member about two orthogonally disposed transverse axes relative to the frame member as well as for axially translating the stage member relative to the frame member. A pair of orthogonally opposed transverse actuators are grounded in the frame member and oriented to provide for transverse translation of the stage member relative to the frame member.Type: GrantFiled: January 25, 1994Date of Patent: March 28, 1995Assignee: New Focus, Inc.Inventors: David F.
