Silica Optical Fibers Feature Non-Circular Core

The company’s non-circular core silica optical fibers target applications in material processing and astronomy. Allegedly, their square fiber offers a more stable means of transmission than that of a circular core fiber as the spatial power distribution is more constant. Good image scrambling is characteristic of the square core fiber as well as low focal ratio degradation. Teaming with diode lasers, which give a square-shaped output, the square core fibers offer greater coupling efficiencies and a homogeneous power distribution on the output end. In these apps, the square output beam reduces the need for beam shaping optics. The square-core fibers are available with edge lengths from 50 to 1,000 microns in NAs from 0.12 to 0.37 and wavelengths from deep UV to NIR. Other shapes are also available.
