30um 50um 70um 0.56NA 0.64NA High numerical aperture (NA) optical fibers

OPTICAL FIBER Optical Fiber is made up of two materials; a high-refractive-index core, and a low-refractive-index cladding.

Light that is injected into one end of an optical fiber can travel through it with little attenuation (signal loss).

However, the amount of signal loss depends on the color of the light, the design of the optical fiber, the materials used,

and the manufacturing configuration and process controls.

High numerical aperture (NA) optical fibers have many uses, for example, for the efficient collection of light
in multimode structures, for fluorescence monitoring and for double-clad fiber lasers. In high-power fiber lasers, low-bright
ness high-power laser diodes are coupled into the high NA inner cladding of a double-clad fiber with a doped core. Raising
the NA of the inner cladding allows the same pump power to be coupled into a smaller diameter inner cladding. This improves
the pump absorption by increasing the overlap of the pump light with the doped core. For collection of light from diffuse sources
and transmission to remote detection equipment, increasing the NA increases the amount of light captured for a certain fiber
diameter.
In order to achieve a large NA, one must arrange for a core and cladding material of widely differing indexes.
Unfortunately, the range of indexes available in transparent solids (including glass and plastics) is relatively small,
the lowest attainable value being approximately 1.3.
For a core of silica glass, this yields a maximum NA of the order of 0.6. In practice, NAs above 0.4 are extremely uncommon in silica fibers.
