We present what is, to the best of our knowledge, the first systematic study on how negative core–cladding index difference influences microstructured optical fiber’s modal behavior. Single-mode lasing has been realized for short-length cladding-pumped phosphate glass microstructured fibers with large depressed-index Er3+Yb3+-codoped cores.

Calculated fundamental mode distributions for MOF7s: Δ n = 7 × 10 4 , d AH Λ = 0.15 , with (a) three, (b) four, and (c) five rings of holes. All three MOF7s have the same ( 70 % ) confinement for the fundamental mode. (d) Comparison between a MOF7 and a MOF1 with the same core area demonstrates that the MOF1 demands a much larger physical size.
