Abstract: An optical device may comprise an optical element holder that holds an optical element in an internal portion of the optical element holder, wherein the optical element holder includes a protruding feature with a contact portion that holds the optical element in the internal portion of the optical element holder. The optical device may additionally comprise the optical element, wherein an edge of the optical element includes a chamfered portion that contacts the contact portion of the protruding feature of the optical element holder to allow the protruding feature of the optical element holder to hold the optical element in the internal portion of the optical element holder.

Abstract: An optical fiber endcap device may include an input facet spliced onto an input fiber and an output end through which counterpropagating light enters the optical fiber endcap device. The optical fiber endcap device further includes a plurality of angled facets that are arranged at respective angles relative to an axis of the optical fiber endcap device to reflect at least a portion of the counterpropagating light back through the output end of the optical fiber endcap device.

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.
