Page 1 of 1 Tapered Optical Waveguides FO-T Series FO-T Series products incorporate a fiberoptic taper which is a dielectric waveguide with a radii that varies with length. As high power laser input devices, they have an input core diameter that is larger than the output core diameter. Used in the opposite direction, they can be output devices to lower the emerging NA, or up taper on a standard fiberoptic to increase the accepting NA, useful in Laser Diode and sensing applications. Features and Benefits Lower surface energy density reduces surface damage. Reduces dielectric breakdown of the Sizes: FO-T Series products are available in input to output core ratios of 10:1 or 1:10 depending on whether it is an up or down taper. Lengths: Down tapers are made separately, and fused to the desired fiber, if a fiber pigtail is desired, while up tapers are usually fabricated directly onto the fiber selected. In either case, any length unit can be provided. Materials: Fused Silica or Borosilicate Glass ORDERING INFORMATION air Folded focal point reduces the potential of self-focusing. Allows for simpler input optics and easier alignment Increase or decrease NA Optimum shape for high pressure optical feedthroughs Fused silica taper assemblies can achieve 2 x 109 Watts/cm2 at the output end of a 600 m core fiber at 1060 nm using 15 ns pulses. FO-T Series products need to be specified with regard to their sizes, lengths, fiber type and end terminations. The input size is the core diameter of the taper input. The output size is the core diameter of the taper output. If the taper is part of, or to be pigtailed to a fiberoptic, the output size will be the fiber core size. The fiber type is the same as the material type for the taper and can be fused silica (UV-VIS, VIS-NIR, Other) or Borosilicate Glass. The end terminations will be a 3/8" or 1/4" diameter ferrule for any standard fiberoptic connectors. NOTE: FO-T Series products can be custom fabricated for a variety of environmental or dimensional requirements. Applications Laser ignition Laser calibration systems LIDAR and other low divergence, low energy, detection systems Diffuse signal collection in sensing systems such as bio-fluorescence High pressure optical feedthroughs Telescopes, space research, optical instruments FOR ADDITIONAL INFORMATION ON THIS OR OTHER PRODUCTS AND THEIR AVAILABILITY, PLEASE CONTACT FIBER OPTIC CENTER, INC.
