Optical Tapers

Fiberguide’s 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.
