文摘

A novel few-mode large-mode-area fiber is proposed. Structural parameters about few-mode and effective area of fundamental mode are investigated in detail. Few-mode condition keeps strict dual-mode with appropriate parameters. Large effective area over 1400 μm2 is achieved with low bending loss less than 10−3 dB/m.
