Abstract
An elliptical multilayer-core fiber (EMCF) with low nonlinearity for wide-band dual-mode operation was proposed. The EMCF, in which only the HE11 and HE21 modes could be propagated, supported a distinct dual-mode operation. The characteristics of the EMCF, including modal properties, the operating wavelength, the transmission loss, the effective area, and the bending loss, were systematically investigated. For EMCFs, a large modal diameter (33.48  μm) was achieved to reduce the fiber nonlinear penalty; meanwhile, the bending loss could be kept in a lower level. In addition, the single-polarization property in EMCFs could be realized by combining stress applying elements.
