摘要：An optical fiber preform, and method for fabricating, having a first core, asecond core spaced from the first core and first and second regions, the first regionhaving an outer perimeter having a first substantially straight length and the secondregion having an outer perimeter having a second substantially straight length facing thefirst straight length. One of the regions can comprise the first core and the othercomprises the second core. The preform can be drawn with rotation to provide a fiberwherein a first core of the fiber is multimode at a selected wavelength of operation and asecond core of the fiber is spaced from and winds around the first core and has aselected longitudinal pitch. The second core of the fiber can couple to a higher ordermode of the first core and increase the attenuation thereof.
