    摘要： An optical waveguide fiber having a high threshold for stimulated Brillouin scattering. According to some embodiments of the invention, the optical fiber comprises: (a) a rare earth doped core having a refractive index profile and a centerline, the core including at least two adjacent core regions including different amounts of updopants, such that the longitudinal acoustic field velocities within the two core regions differ by at least 0.2%; and (b) a cladding layer surrounding and directly adjacent the core. The said fiber has MFD of greater than 12 μm and delta % difference between the peak core delta and the cladding of less than 0.3%.

    摘要： According to one embodiment a method of making optical fibers comprises: (i) manufacturing a core cane; (ii) situating a plurality of microstructures selected from rods, air filled tubes and glass filed tubes and placing said microstructures adjacent to the core cane, said microstructures forming no more than 3 layers; (iii) placing the core cane with said adjacent microstructures inside a holding clad tube; and (iv) placing interstitial cladding rods inside the holding (clad) tube, thereby forming an assembly comprising a tube containing a core cane, a plurality of microstructures and interstitial cladding rods. The assembly is then drawn into a microstructured cane and an optical fiber is drawn from the microstructured cane. According to several embodiments, the method of making an optical fiber includes providing at least one air hole and at least one stress rod adjacent to the core.
