Abstract: Spliced multi-clad optical fibers with a cladding light stripper (CLS) encapsulating the splice. The splice may facilitate conversion between two optical fibers having different architectures, such as different core and/or cladding dimensions. The CLS may comprise a first length of fiber on a first side of the splice, and a second length of fiber on a second side of the splice, encapsulating the splice within the lengths of the CLS. The splice may abut one or more of the lengths of the CLS, or may be separated from one or more lengths of the CLS by an intermediate length of a first and/or second fiber joined by the splice.

Abstract: An apparatus includes a laser system that includes a first fiber having an output end and situated to propagate a first laser beam with a first beam parameter product (bpp) and a second fiber having an input end spliced to the output end of the first fiber at a fiber splice so as to receive the first laser beam and to form a second laser beam having a second bpp that is greater than the first bpp, wherein the output end of the first fiber and the input end of the second fiber are spliced at a tilt angle so as to increase the first bpp to the second bpp.

Abstract: An apparatus includes a camera, a dark field illumination source, and a fiber inspection housing including a fiber connector input situated to receive an optical fiber connector so that an optical fiber output end of the optical fiber connector is removably insertable into an interior region of the fiber inspection housing and securable at a predetermined location in the interior region, a camera input situated to receive and secure the camera so that the camera is in optical communication with the interior region and the optical fiber output end, and a dark field illumination source input situated to receive the dark field illumination source so that light emitted from the dark field illumination source is received by the optical fiber output end at a dark field illumination angle and is scattered by contamination or defects associated with the optical fiber output end so as to be detectable by the camera.

Abstract: Multi-clad optical fiber cladding light stripper (CLS) comprising an inner cladding with one or more recessed surface regions to remove light propagating within the inner cladding. A CLS may comprise such recessed surface regions along two or more azimuthal angles about the fiber axis, for example to improve stripping efficiency. One or more dimensions, or spatial distribution, of the recessed surface regions may be randomized, for example to improve stripping uniformity across a multiplicity of modes propagating within a cladding. Adjacent recessed surface regions may abut, for example, end-to-end, as segments of a recess that occupies a majority, or even an entirety, of the length of a fiber surrounded by a heat sink. One or more dimensions, or angular position, of individual ones of the abutted recessed surface regions may vary, according to a regular or irregular pattern.
