Definition
Optical or glass fibers can be used for many different applications, with the main purpose to transport light over a certain distance. Optical fibers consist mainly of a core with a certain diameter, a cladding and a coating. In standard optical fibers, the difference in refractive index between the solid cladding and the solid core with a certain diameter is used to guide light through the fiber.

Single mode (SM) optical fibers feature a small diameter of the fiber core (in the range of 2.5 µm to 10 µm), supporting mode field diameters from 2 µm (320 nm) up to 9 µm (1550 nm) and allowing propagation of light in just one (transversal or fundamental) optical mode which will not undergo dispersion effects causing signal distortion over long distances.

Multi mode (MM) optical fibers are used for applications where it is important to transmit as much light as possible, mostly for illumination purposes. They feature relatively large core diameters, usually in the range of 50 µm up to 1000 µm. Depending on the wavelength of the light, these diameters allow multiple modes of light to propagate through the fiber. Due to interference effects, light pulses get distorted when travelling through a MM fiber over longer distances.

For some applications where maintaining the light’s polarization is key, a polarization maintaining (PM) fiber is used. In most versions of this single-mode specialty fiber, tension rods are integrated into the fiber’s cladding on opposite sides of the core, inducing a strong but tightly controlled birefringence. If linearly polarized light is properly launched into a PM fiber it maintains its linear polarization during propagation.

Doped fibers are often called active fibers. Their cores are doped with laser-active ions, mostly of rare-earth materials like Erbium (Er), Ytterbium (Yb), Neodymium (Nd) or Thulium (Tm). Pumped with suitable pump sources like flash lamps, LEDs or diode lasers by a typically shorter wavelength, these ions absorb the pump light and get excited into some metastable energy levels.

Compared to optical fibers with cores made of silica or composite glass, plastic optical fibers (POF) are entirely made of polymer materials. Not only coatings and jackets, but also fiber core and cladding consist of polymers. While showing higher attenuation and lower transmission capacity, plastic optical fibers are less brittle, more flexible, easier to handle and very cost-effective. Typical areas of use are short-range data communications, illumination and industrial applications.

Special micro-structured optical fibers guide light using structural modifications – in most cases holes or inclusions of a material with different refractive index in the core and/or in the cladding, periodically and evenly distributed over a large part of the cross-sectional area of the fiber. Typical representatives of micro-structured optical fibers are photonic crystal fibers (PCF) or photonic bandgap fibers.

To protect optical fibers against higher temperatures, they can be coated with different materials like acrylate (for medium temperature levels), aluminium or gold, making the fibers usable in harsh environments. If further protection is needed, an additional flexible metal tube will make them even more durable, especially for industrial applications.

The performance of an optical fiber can be enhanced by antireflecting coatings at the fiber’s end face. A special plasma-based nano-structuring technology can raise the damage threshold of the fiber for selected fibers. Shaped fiber tips or endcaps are further options to improve the performance of the fiber-to-air interface.

AFT/SFT Optical Fiber Tapers
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.
