Abstract
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 LPN and LP11 modes in 1.3 gm wavelength region. In addition, we have incorporated the concept of effective cut-off, of the LP02 mode, 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 μm to 1.36 μm). Hence the predicted bandwidth of the bimodal fiber is high, over a broad wavelength interval.
