Abstract: 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.

Abstract: A graded index fiber having a refractive index profile that causes a beam to be re-imaged in the graded index fiber with a regular period may include a set of bends that have a bend period matched to or nearly matched to a pitch of the graded index fiber. For example, the set of bends may be formed in the graded index fiber using one or more bending devices that include one or more protrusions that have a periodicity matched to or nearly matched to a pitch of the graded index fiber. A first section of the one or more bending devices may be actuated to move towards a second section of the one or more bending devices such that the one or more protrusions cause the bends to be formed in the graded index fiber.

Abstract: An optical fiber may include a core in which core-guided light generated by one or more light sources propagates along a length of the at least one optical fiber, one or more claddings, surrounding the core, to guide cladding-guided light generated by the one or more light sources along the length of the at least one optical fiber, and a reflector structure machined into the at least one optical fiber. The reflector structure may include multiple angled facets arranged at one or more respective angles relative to an axis of the optical fiber to reflect at least a portion of the core-guided light and/or the cladding-guided light passing through the optical fiber.

Abstract: An optical device may include a fiber to provide a beam. The optical device may include a graded-index element to expand or magnify the beam. An input facet of the graded-index element may be adhered to an output facet of the fiber. The optical device may include an optical transformation element to transform the beam after the beam is expanded or magnified by the graded-index element. An input facet of the optical transformation element may be adhered to an output facet of the graded-index element.

Abstract: In some implementations, an apparatus for aligning multiple fibers may comprise a lattice structure that comprises a plurality of tensioned elements to provide a deformable support framework to simultaneously position a plurality of optical fibers such that the plurality of optical fibers is elastically constrained in a first axis and a second axis. The apparatus may further comprise an array that comprises a plurality of micro-jaw structures passing through the lattice structure. In some implementations, each micro-jaw structure in the array of micro-jaw structures is adjustable to shift one or more positions of one or more optical fibers included among the plurality of optical fibers relative to one or more cores of a multi-core optical fiber.

Abstract: In some implementations, an optical device may include a first optical element, wherein the first optical element is a first prism. The optical device may include a second optical element, wherein the second optical element is a second prism, and wherein the optical device is configured to receive a beam and output the beam. The first optical element and the second optical element may be configured to alter a beam shape of the beam, such that the beam has a first shape at a first location and a second shape at a second location.

Abstract: In some implementations, a fiber processing machine may receive an optical assembly comprising an input fiber, an output fiber, and a graded index fiber spliced between the input fiber and the output fiber, wherein the graded index fiber has a pitch length and a processed length. A light source may deliver input light into an input end of the input fiber while one or more components monitor output light at an output end of the output fiber. The fiber processing machine may alter a core diameter and the processed length of the graded index fiber until one or more measurements of the output light at the output end of the output fiber indicate that the output light is a perfect image of the input light.

Abstract: In some implementations, a master oscillator power amplifier (MOPA) system may include one or more pump laser sources, a power amplifier, and a multicore oscillator that includes an input side coupled to the one or more pump laser sources and an output side coupled to the power amplifier. In some implementations, the multicore oscillator may include an active fiber, including an inner cladding, an outer cladding surrounding the inner cladding, and multiple active fiber cores, embedded in the inner cladding, to convert pump light into signal light. In some implementations, the multicore oscillator may include multiple first reflectors that are each configured to operate as a high reflector on the input side of the oscillator, and multiple second reflectors that are each configured to operate as an output coupler on the output side of the oscillator.

Abstract: 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.
