The present disclosure relates to a fiber optic component including a ferrule having a distal end and a proximal end. The ferrule defines a fiber passage extending though the ferrule along a fiber passage axis in a proximal-to-distal orientation. The fiber optic component also includes an optical fiber structure affixed within the fiber passage. The optical fiber structure includes a beam expansion section optically coupled to a sacrificial section. The beam expansion section has a construction adapted to expand an optical beam from a first beam diameter to an enlarged second beam diameter. The sacrificial section is configured to receive the optical beam having the second beam diameter from the beam expansion section. The sacrificial section is positioned at the distal end of the ferrule and has a polished end face at the distal end of the ferrule. The sacrificial section has a core-less construction or has a core with a core diameter that is larger than the enlarged second beam diameter.

A fiber optic cable and connector assembly is disclosed. In one aspect, the assembly includes a cable optical fiber, an optical fiber stub and a beam expanding fiber segment optically coupled between the cable optical fiber and the optical fiber stub. The optical fiber stub has a constant mode field diameter along its length and has a larger mode field diameter than the cable optical fiber. In another aspect, a fiber optic cable and connector assembly includes a fiber optic connector mounted at the end of a fiber optic cable. The fiber optic connector includes a ferrule assembly including an expanded beam fiber segment supported within the ferrule. The expanded beam fiber segment can be constructed such that the expanded beam fiber segment is polished first and then cleaved to an exact pitch length. The expanded beam fiber segment can be fusion spliced to a single mode optical fiber at a splice location behind the ferrule.

A GRIN fiber lens connection system particularly suited for high-power laser applications is disclosed. In one aspect, a GRIN fiber lens expanded beam system that is efficient over a wide spectral region, e.g., a range of about 200 nm, 300 nm or 400 nm, is disclosed for coupling one optical fiber (such as a single-mode fiber) to another. For example, a GRIN fiber lens expanded beam system is efficient over a range of wavelengths from about 400 nm to about 800 nm, from about 190 nm to about 390 nm, or from about 1270 nm to about 1650 nm. A method for designing such a coupling system is also disclosed. In another example, the cores of the GRIN fiber lenses are substantially devoid of germanium, and the cladding is doped with an element, such as fluorine, that lowers the refractive index of the cladding.

A method and apparatus for aligning optical transports in a ferrule. The transports are aliened in the ferrule by mounting the ferrule on a jig having grooves into which the ends of the optical transports are inserted for transversely aligning the fibers in the ferrule. A row of transports is placed in the ferrule cavity with the front ends of the transports extending past the ferrule and into the grooves of the jig, thereby laterally aligning the transports with the grooves. The fibers are affixed to the ferrule. The ferrule can then be removed from the jig and the front ends of the transports that extended into the grooves of the jig cleaved flush with the front face of the ferrule.

A measurement system comprising an analog position sensitive device is provided that can measure the XY position of a plurality of light beams at very high resolution. In accordance with one exemplary associated method, a connector bearing one or more optical fibers is fixedly positioned before a position sensing detector so that light emanating from the ends of the optical fibers will strike the position sensing detector. A light beam is passed through at least one opening in the connector, such as a guide pin hole onto the detecting surface of the PSD to establish the position of the connector. Next, each optical fiber in the connector is individually illuminated sequentially so that the light emanating from the fiber falls on the position sensing detector. The locations of all of these light beams striking the PSD are compared to position of the light beam passed through the guide pins and/or to each other to determine if all the fibers are in the correct positions relative to the connector. In addition, it is possible to simultaneously measure the magnitude of the light emanating from each fiber in order to measure the quality of the light transmission through the connector/cable assembly.

An optical ferrule comprising: (a) a body defining an end face; (b) one or more channels extending from said end face through said body, each channel adapted to receive an optical fiber; and (c) first and second alignment pin channels defined in said end face, each alignment pin channel having a center point, said center points being disposed along a first axis, said first alignment pin channel having a first cross section essentially the same as that of an alignment pin and being adapted to receive said alignment pin, said second alignment pin channel having a second cross section elongated along said first axis.

Methods and apparatus for aligning optical transports, such as waveguides and optical fibers, in a ferrule of an optical connector. The ferrule has an open side through which optical transports may be inserted into a transport cavity in the ferrule from a direction transverse the longitudinal direction of the optical transports and ferrule. To assemble the optical transports in the ferrule, the ferrule is positioned with its front face abutting and aligned with a jig that has an opening substantially identical to the ferrule cavity. The jig has grooves in a bottom surface of the cavity into which the optical transports will be inserted for transversely aligning the optical transports. The optical transports are then dropped into the aligned cavities of the ferrule and jig through the open sides of the ferrule and jig so that the front ends of the optical transports sit at least partially in the V-shaped grooves of the jig, thereby aligning the transports in the transverse dimension. A press cures adhesive in the cavity to cure the adhesive and fix the transports in the ferrule. The optical transports are then cleaved or otherwise cut flush with the front face of the ferrule. The process is repeated for each row of optical transports with the height of the bottom of the cavity in the jig adjusted for each subsequent row by an amount equal to the thickness of a row of the optical transports.

The invention pertains to a ferrule for aligning optical transports within an optical connector for coupling to a mating optical connector for purposes of aligning the optical transports in the first connector with optical transports in the mating connector. The ferrule comprises a main body portion defining a longitudinal cavity running between a front face and the rear face of the main ferrule body. The cavity has an opening to a lateral side of the ferrule main body that permits the installation of optical transports into the cavity from a lateral direction (as well as still permitting longitudinal installation, if desired). A cover may be provided for closing off the lateral opening after the optical transports are installed in the cavity.
