Large-effectiΒ¨e-area fibers are essential for high-capacity and long-distance links. We report a large-effectiΒ¨e-area dispersionflattened fiber design that proΒ¨ides, oΒ¨er the waΒ¨elength range of 1.48 m --1.58 m, an effectiΒ¨e area of 75α100 m 2 , a mode-field diameter of 9.56α10.92 m, and a chromatic
The 1-hole-missing and 7-hole-missing photonic crystal fibers (PCFs) with flattened fundamental modes (FMs) are proposed by introducing a layer of up-doped silica into the core of the PCFs. The transverse mode competitions are compared between the 7-hole-missing PCF lasers with and without flattened
