  • Patent number: 11762149
    Abstract: A method and apparatus for controlling propagation of a light beam using a beveled endcap of an optical fiber, where the endcap has a first end coupled to the optical fiber and a second end having a bevel that circumscribes a facet. The bevel has an angle relative to the plane of the facet that directs a peripheral portion of the light beam towards a lens and the facet directs a central portion of the light beam towards the lens. As such, the light beam is collimated with substantially all of the power of the light beam propagating through the lens and all the power delivered with fiber core to the output endcap is propagating through the lens despite the divergence of the delivered beam and a restricted aperture of the lens.

  • Patent number: 11670905
    Abstract: Fiber laser amplification systems and methods are disclosed for use with a chirally coupled core (3C) optical fiber enabling the generation of a high-power output beam having a controlled stable polarization state. Vector modulation instabilities which typically induce undesirable sidebands in 3C fiber optics are greatly reduced even at high peak powers, enabling operation of the up to power levels limited mainly by stimulated Raman scattering (SRS). Polarization extinction ratios (PER) demonstrate long-term stability and minimal degradation due to changes in system temperature. Delays in reaching stable operation during start-up are also greatly reduced.

    Abstract: A fiber optic connector assembly incorporates features that improve structural rigidity and the integrity of transmitted signals. These features also facilitate a technique for reversing polarity of the connector assembly with little or no risk of twisting the optical fibers and without requiring the housing assembly to be disassembled. The connector is marked or embossed with transmit and receive connector labels that facilitate visual identification of the polarity of the connector. One side of the duplex connector can be marked with “A” and “B” labels corresponding to the receive and transmit connectors, respectively. The opposite side of the duplex connector can be marked with two “A” labels corresponding to the receive and transmit connectors, respectively. Thus, a user can readily identify whether the connector is configured for “A-B” polarity or “A-A” polarity.

  • Publication number: 20150110446
    Abstract: A fiber optic connector has a connector outer housing and a connector inner housing. The connector inner housing has a projection to interact with a latch on an adapter into which the connector is inserted. The force required to move the connector outer housing relative to the connector inner housing is less than the force to remove the connector inner housing from the latch. A groove or opening may also be formed in the connector outer housing to effectively shorten the connector outer housing and prevent interaction of the latch with the outer housing, reducing debris.

  • Patent number: 8961036
    Abstract: A method for preparing a ferrule assembly avoids polishing while providing adequate control over fiber end protrusion and co-planarity. A distal end of the fiber is prepared before securing the fiber in a ferrule, and before or after inserting the fiber into the ferrule. The prepared fiber is manipulated to provide a desired spatial relationship between the fiber end and the ferrule's end face, and then secured to maintain the desired spatial relationship. Preferably, the fiber end is prepared using a laser cleaving technique to provide a suitable end without abrasive polishing. An interferometer may be used to obtain measurements, during manipulation of the prepared fiber within the ferrule, that indicate whether the prepared fiber is satisfactorily positioned. In accordance with other aspects of the invention, a ferrule assembly prepared in accordance with the method, and a connector or other optical package including such a ferrule assembly are provided.
