Optran® NCF UV, Optran® NCF WFSilica / silica non-circular fiberPure fused silica / F-doped fused silica square and rectangular shaped fibersFibers which deviate from the traditional round form with a square or rectangular shape offers advantages due to providing maximum packing density for input and output. These fibers are very suitable for connections to angular sources and receivers, e.g. diode lasers. The angular shaped core provides consistent short-distance homogenization input power distribution. Our angular fibers are also available in rectangular shapes with large side ratios and a small corner radius, thanks to our special PCVD-technology.

Large NCF's are ideal for applications which require a combination of flexibility and large cross sections in silica fibers, e.g. a diode laser delivery system. To name an example, the geometry of a rectangular optical fiber with a ratio of 1 : 3 allows for rotation and movement on one axis. The cross section is but about four times larger than that of a round fiber (round fiber /diameter – rectangular fiber / page size).

Advantages Maximum packing density for input or output of bundle Suitable for diode laser coupling Homogeneous power distribution Wide range of available core and cladding sizes The same cross section ratio of the core provides higher flexibility compared to round fibers High resistance against laser damage No need for laser beam focusing optics Very low NA-expansion Excellent image scrambling characteristics Step-index profile

ApplicationsExcellent choice for applications that include diode laser coupling and many more.

FormulaA tapered optical fiber acts as a beam diameter and numerical aperture converter, with the input beam being converted according to the following formula:

NA1: Input NA | NA2: Output NAD1: Input diameter | D2: Output diameterThe output NA is limited by the NA of the fiber used, which may result in a loss of light.

21 CUSTOMER INFORMATION

Instructions for useFibers, fiber cables, fiber bundles

Please note the following information to ensure the long-term safe use of your fiber products:

Safety1. The NA of the laser beam must be smaller than the NA of the fiber.2. The laser beam must be precisely directed towards the core diameter or fused bundle, as connectors or adhesive between the bundles may otherwise overheat.3. It is recommended to have the laser energy distributed evenly (instead of a Gaussian distribution).

Application1. Clean the fiber endface before switching on the laser.2. Ensure that the ferrule and receptacle are entirely free from any contamination, as contaminants may burn in.3. The cable / bundle surface may be cleaned with isopropyl alcohol, ideally under a microscope using a cotton bud.4. Ensure that the optical axes are correctly aligned and not at an angle to each other, and that the focal point is correctly aligned. It is recommended to verify the alignment using a He-Ne laser.5. Ensure that the minimum bending radius is complied with to prevent fiber breakage.

22 CUSTOMER INFORMATION

CeramOptec® glossary We have explained some important concepts of fiber optics below.

Please do not hesitate to contact us if you have any questions.

Fiber optics The branch of optical technology concerned with the transmission of radiant power through fibers made of transparent materials such as glass, fused silica or plastic.

Optical fiber (Also optical waveguide, fiber optic cable, optical cable) – a thin filament of drawn or extruded glass or plastic having a central core and a cladding of lower-index material to promote internal reflection.

Fiber bundle A rigid or flexible, concentrated assembly of glass or plastic fibers used to transmit light.

Core The light conducting portion of an optical fiber. It has a higher refractive index than the cladding.

Cladding Low refractive index material that surrounds the core of an optical fiber. It contains the core light while protecting against surface scattering. The cladding can consist of fused silica, plastic or specialty materials.

Numerical aperture (NA) In fiber optics, the NA describes the range of angles at which light can enter and exit the system. NA is an important parameter in applied fiber optics.

Ultraviolet The invisible region of the spectrum beyond the violet end of the visible region. Wavelengths range from 1 to 400 nm.

Visible spectrum The region of the electromagnetic spectrum to which the retina is sensitive and by which the eye sees. It extends from about 400 to 700 nm in wavelength.

Attenuation The phenomenon of the loss of average optical power in an optical fiber or medium.

Bend loss Loss of power in an optical fiber due to bending of the fiber. Usually caused by exceeding the critical angle required for total internal reflection by internal light paths.

Transmission In optics, the conduction of radiant energy through a medium. Often denotes the percentage of energy passing through an element or system relative to the amount that entered.
