Publication number: 20240036255Abstract: A system may perform an uptapering process to cause a signal fiber to have a fiber core with a first uptapered thickness profile and a fiber cladding with a second uptapered thickness profile. The system may perform, after performing the uptapering process, an uptapering removal process to cause the fiber cladding of the signal fiber to not have the second uptapered thickness profile. The system may perform, after performing the uptapering removal process, a bundling process to bundle the signal fiber and a set of one or more pump fibers in a bundle configuration. The system may perform, after performing the bundling process, a bundle unification process to cause the bundle configuration to form a unified bundle configuration. The system may perform, after performing the bundle unification process, an attachment process to cause an end of the unified bundle configuration to attach to an end of an output fiber.Type: ApplicationFiled: September 28, 2022Publication date: February 1, 2024Inventors: Ning LIU, Jeff GREGG, Gongwen ZHU, Xiang PENG, Guan SUN, Matthew KUTSURIS

Publication number: 20230333315Abstract: A laser component includes a pump-signal combiner, which includes a first capillary, a plurality of pump fibers, a second capillary, and a signal fiber. The plurality of pump fibers, the second capillary, and the signal fiber are arranged in a bundle configuration. The bundle configuration is disposed within an internal portion of the first capillary. A cross-section of the bundle configuration includes an outer area, in which the plurality of pump fibers are disposed, and an inner area, in which the second capillary and the signal fiber are disposed. The signal fiber is disposed within an internal portion of the second capillary.Type: ApplicationFiled: June 30, 2022Publication date: October 19, 2023Inventors: Patrick GREGG, Richard D. FAULHABER, Martin H. MUENDEL, Jeff GREGG, Kyle R. SCHNEIDER

Patent number: 11619788Abstract: In some implementations, a fiber optic combiner may comprise an enclosing tube having a geometric shape and multiple optical fibers bundled within the enclosing tube. In some implementations, the multiple fibers comprise at least one optical fiber having a core and a non-circular cladding surrounding the core. The non-circular cladding may cause the multiple optical fibers to have a larger tube fill factor and a lower expected beam parameter product increase factor relative to the multiple optical fibers all having circular claddings.Type: GrantFiled: June 29, 2021Date of Patent: April 4, 2023Assignee: Lumentum Operations LLCInventors: Martin H. Muendel, Patrick Gregg, Richard D. Faulhaber, Jeff Gregg, James J. Morehead

Patent number: 11592612Abstract: In some implementations, a waveguide may comprise an inner core to receive a first beam and an outer core surrounding the inner core to receive a second beam that is displaced from the first beam by an offset. The outer core may comprise a beam guiding region that rotationally expands over a length of the waveguide into an annulus that concentrically surrounds the inner core or a partial annulus that partially surrounds the inner core. For example, the beam guiding region may be defined by one or more low refractive index features that have a varied orientation and/or a varied shape over the length of the waveguide such that the second beam enters the waveguide as an offset beam and exits from the waveguide as a ring-shaped beam or a partial ring-shaped beam.Type: GrantFiled: March 2, 2021Date of Patent: February 28, 2023Assignee: Lumentum Operations LLCInventors: Patrick Gregg, Martin H. Muendel, Richard D. Faulhaber, James J. Morehead, Jeff Gregg

Patent number: 11415751Abstract: An optical fiber includes a core configured to transmit laser light and a cladding that surrounds the core. In some implementations, an outer surface region of the cladding is tapered or comprises a plurality of notches. The outer surface region of the cladding is configured to cause an aiming beam that falls incident upon the outer surface region of the cladding at a first incidence angle to fall incident upon an outer surface region of the core at a second incidence angle to allow the aiming beam to couple into the core.Type: GrantFiled: February 4, 2021Date of Patent: August 16, 2022Assignee: Lumentum Operations LLCInventors: Jeff Gregg, Xiang Peng, Richard D.

Patent number: 8123251Abstract: An adjustable steering column assembly for a vehicle preferably has a bracket for rigid attachment to the vehicle with a first slot defining a longitudinal adjustment path of the assembly. A steering shaft is journaled to a jacket of the assembly for rotation about an axis. A shuttle attaches rigidly to the jacket and adjustably to the bracket for telescoping and tilt adjustment of the assembly. The shuttle has a second slot that defines a collapse path with said second slot preferably having a first portion restraining said steering shaft in a normal state and a second portion that allows said steering shaft to move through said collapse path when in a collapsed state. A pin extends through said first and second slots for coupling said shuttle to said bracket.Type: GrantFiled: December 17, 2009Date of Patent: February 28, 2012Assignee: Steering Solutions IP Holding CompanyInventors: Leland N. Olgren, Michael S. Gregus, Donald A. Niedzielski, Germaine Niedzielski, legal representative, Roger A. Bourbina, Jeff A. Gregg

Patent number: 7914043Abstract: The present invention provides for a steering column assembly having a column jacket defining a longitudinal axis. A first clamping member and a second clamping member are disposed along the longitudinal axis about the column jacket. A lever is coupled to one of the first and second clamping members and rotatable between a set and adjustable positions. The lever includes a first arm and a second arm flanking the column jacket and coupled to at least one of the first and second clamping members with a portion of the locking device disposed about at least one of the first and second clamping members and engaging both of the first and second arms such that rotation of the lever moves the portion of the locking device for minimizing rotation of the lever between the set and adjustable positions when the locking device moves between a locked and unlocked positions.Type: GrantFiled: April 7, 2008Date of Patent: March 29, 2011Inventors: Leland N.
