Abstract

Characteristics of few-mode multi-core fiber (FM-MCF) were numerically analyzed and experimentally confirmed. The cores of FM-MCF were designed to support transmission of LP₀₁ and LP₁₁ modes from the point of bending loss of LP₁₁ and LP₂₁ modes. Inter-core crosstalk between LP₁₁ mode was calculated to determine core pitch of fibers. It was confirmed that the fabricated fibers was two-mode transmission over C-band and L-band with the effective area of LP₀₁ mode of about 110 μm² at 1550 nm. The crosstalk of the fibers was estimated to be smaller than −30 dB at 1550 nm after 100-km propagation. The crosstalk dependence on wavelength was also measured and matched well with the simulated results.
