Design and computer analysis of bimodal heavy metal fluoride fibers in the 1.3 xm wavelength region
Date of Original Version
We have studied the design of heavy metal fluoride fibers, having segmented-core refractive index profiles, and operating in a bimodal regime, with small modal dispersion, or good equalization, between the LP01and LP11modes in 1.3 µm wavelength region. In addition, we have incorporated the concept of effective cut-off, of the LP02mode, in order to maximize the operating V value. A practical bimodal equalized design example, which has negligible extrinsic losses, is provided in which the equalization between the modes is within ± 25 ps/km over a wavelength interval of 160 nm (˜ 1.2 pm to 1.36 µm). Hence the predicted bandwidth of the bimodal fiber is high, over a broad wavelength interval. © 1990 SPIE.
