Polarisation-maintaining optical fibres with low dispersion over a wide spectral range.
Applied Optics, 22, . (doi:10.1364/AO.22.002370).
The total dispersion characteristics of the doubly clad Panda (or bow-tie) fibers have been investigated. It is shown that the contribution of the photoelastic effect to the total dispersion becomes of the order of several psec/km.nm in the 1.5-1.7-µm wavelength region. By careful adjustment of the cutoff wavelength, the total dispersion is reduced to within ±1 psec/km.nm over the 1.38-1.70-µm wavelength region for the HEx(11) mode and 1.38-1.68 µm for the HEy(11) mode, respectively.
