Shaped Fiber Tip Assemblies

Receptacle Style; 180 to 2000 nm; Coupling Efficiency >60% to >80%; Backreflection -14 to -60 dB; Power Handling >1 to >100 W In OZ Optics' HPUC series of receptacle style, non-contact style laser to fiber couplers, an air gap exists between the fiber and the lens. This design is more flexible, allowing a wide range of lens types and focal lengths to be used. The distance between the fiber and the lens can be adjusted to compensate the changes in the source wavelengths or to intentionally defocus the laser beam to prevent arcing in high power laser to multimode fiber applications. Couplers using GRIN lenses, achromats, aspheres, fused silica, plano-convex, and biconvex lenses have all been made utilizing this design. Non-contact style couplers can handle input powers of up to 100 W CW, and even higher energies from pulsed sources. They are best suited for applications where either the input energy is higher than 400 mW, or when more than one wavelength is to be coupled into the fiber, or for input beams that have unusually large beam diameters or divergence angles. They also have superior polarization maintaining capabilities compared to physical contact style couplers. However because of the air gap between the fiber and the lens, the backreflection level for the endface of the fiber is about -14 dB. This can be reduced to -40 dB to -60 dB by slant polishing both fiber ends to deflect the backreflected signal. There is a significant variation in the endface geometries of angled PC (APC) connectors. This effects the spacing between the endface of the fiber and the lens. To minimize this variation, OZ Optics offers an angled flat (AFC) connector. This connector features a beveled endface where the fiber itself is angled but the ferrule tip is flat. This geometry provides optimum repeatability between connections. For users of SMA connectors, please note that standard SMA connectors and receptacles are constructed to rather loose tolerances, leading to poor repeatability. For core diameters of 100 µm or smaller, we recommend using SMA connectors with Zirconia ferrules and receptacles with Zirconia sleeves. This will give maximum repeatability. Better still, consider using FC connectors instead.

Fiber Type Single Mode, Multi Mode Step & Graded Index; Input Core Diameter 100 to 600 µm; Output Core Diameter 50 to 200 µm; Numerical Aperture 0.12, 0.26; Wavelength 180 to 2400 nm; Sheathing PVC, Stainless SteelFiberguide’s AFT/SFT series of optical tapers are used for mode mixing, lowering optical power density in high power applications, and converting numerical aperture (NA) in optical power delivery applications. Optical tapers can either be tower drawn, where the length is several meters, or they can be produced using bench-top equipment, making the length a few inches. In both cases, these optical tapers are continuous pieces of fiber, they are not spliced. Tapered optical fibers can be made either by fusing a short tapered section onto a longer fixed diameter fiber or by very carefully controlling the drawing process to produce a single continuous fiber with an integral tapered section. For its AFT/SFT series, Fiberguide uses the latter process since it results in superior fiber strength, alignment precision and optical power transmission. Tapered optical fibers cause optical mode mixing that tends to homogenize spatial power distribution. A larger input core diameter can prevent input damage and allow a smaller diameter pigtail for convenience in adapting to a wide range of optical applications. Tapered optical fibers can be used as a passive optical component to alter the input and / or output divergence (N.A.) with regard to an optical fiber, as a high power coupler for laser energy, as this will spread the energy over a larger area, or simply as a device to relax tolerances in an optical system. To ensure maximum efficiency of light transmission, the numerical aperture (N.A.) of the light entering the taper input should be 0.22 divided by the taper ratio. As an example, assume the input core diameter of the taper is 400 µm and the output core is 200 µm (2:1 taper ratio), then the N.A. of the light entering the taper will be 0.22/2 = 0.11.Additionally, the fibers can be equipped on demand with Fiberguide’s patented RARe Motheye anti-reflective technology that enhances fiber transmission performance and significantly increases the damage threshold for your application over a large wavelength range.

Manufacturing of Optical Fiber Tapers, Couplers, Combiners; “Ring of Fire” Heat Source for Even Heating; Integrated Cleaver for ≤500 µm Dia. Fibers; Flow 126 l/min; Pressure 0.4-0.6 Pa 3SAE Technologies’ TMS Taper Manufacturing System with an integrated cleaver is the supplier’s most advanced optical fiber tapering system that provides easy fiber access, unparalleled heating source control, stiction-free pulling results in the highest quality, lowest loss and best repeatability. The production-ready TMS system is specifically designed to maintain production-level repeatability for manufacturing of optical fiber tapers, couplers and multi-kilowatt class high-power fiber combiners. The TMS operates in partial vacuum (advantageous in producing adiabatic fiber tapers) and is utilizing the patent pending “Thermally Stabilized Plasma™” technology, which generates a wide and extremely stabilized heat source with a wide dynamic range of operation from <300 to >3000 °C. This allows the width of the plasma field to expand up to 10x along the axis of the fiber. While narrow profiles create modulations and stress concentrations that induce losses, heat sources with a wider heat profile are better for tapering and bundling of fibers because the pull distance per unit time is distributed over the molten region in accordance with the profile. The TMS system’s wider plasma field flattens and reduces the frequency of modulations in a taper, resulting in ultra-low losses <1%. Operating in partial vacuum also minimizes oxidation of the electrodes during the tapering process, resulting in virtually debris free tapers. 3SAE Technologies’ blunt electrode design increases life expectancy by >10x while increasing throughput power capabilities for high-power laser systems. High-power testing confirms that TMS does not contaminate the glass surface, eliminating the need for etching and reducing the cost of production and rework. Three customizable tapering modes are available: single direction, bi-directional and table-based tapering. Table-based tapering allows the flexibility of a syntax-based software program to create a custom taper program while using a simplified LabVIEW-based GUI. Alternately, programs such as "MATLAB" or Microsoft Excel can be utilized to develop the tapering program.

Fiber Type Step Index MM, Other; Wavelength 190 to 2400 nm; Sheathing Stainless Steel Monocoil (Bare or PVC Coated); Termination High Power SMA, High Power FD-80Fiberguide’s end capped high power fiber optic assemblies allow the user to achieve higher coupled power into a fiber core by reducing the power density at the air/ silica interface, commonly the point of laser damage. End cap diameters and lengths are offered for select numerical apertures and fiber core sizes but can be easily customized for a variety of fiber types and specialized applications. End capped high power assemblies allow for much higher transmitted powers by reducing the power density to a level below the damage threshold. Their shaped endcap tips can be tailored to specific laser launch conditions and applications. Fiberguide’s proprietary laser polishing process minimizes surface imperfections and maximizes power handling. High Power SMA and D-80 compatible connector options offer superior thermal management while minimizing connector stress for NA conservation. With their epoxy-free cantilevered nose design (available in select versions), Fiberguide’s end capped high power assemblies allow thermal energy to safely dissipate and thus minimize laser and heat damage to surrounding materials Fiberguide offers end capped high power assemblies for a broad range of step index multi mode fibers, including AFS/AFM/AFH/SFS/SFM/SFH all silica optical fiber, AFSH/SFSH hard polymer coat fiber, APC/SPC polymer clad fiber, APCH/SPCH hard clad fiber, AFR/SFR Uniclad™ high power fiber or Solarguide™ solarization resistant fiber.
