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 LP01 and LPn modes in the 1.3 μm wavelength region. In addition, we have incorporated the concept of effective cutoff, of the LPO2 mode, in order the 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 (∼ 1.2-1.36 μm). Hence, the predicted bandwidth of the bimodal fiber is high, over a broad wavelength interval. © 1990 IEEE
