Figure 3 of Ref [1] contains some mistakes because of the incorrect calculation. The authors very apologize for the carelessness. This error does not affect the results of Ref [1]. The corrected Fig. 3 in [1] should be:

In [1], the changes in the comparisons are shown in bold.

In the last paragraph of Section 2, the statement should be corrected to:

“According to the calculated results, the suspended core modes can be excited strongly with the increasing lateral-offset. The excitation coefficient of LP₁₁ mode in the center core shows a trend of growth and then decline with the increasing lateral-offset, and its excitation efficiency reaches a maximum when the lateral-offset is ~4 μm. In addition, when the lateral-offset exceeds ~4.4 μm at 980 nm, the LP₁₁ mode is excited mainly in center core due to the larger excitation coefficient than that of LP₀₁ mode. When the lateral-offset reaches ~8 μm, the LP₁₁ modes in the center core and suspended core can be excited almost equally. At 1310 nm, the tendency of excitation coefficients of modes is similar to the situation at 980 nm. It is noteworthy that excitation coefficients of every mode are higher than those with same lateral-offset at 980 nm. It can be attributed to the larger effective mode field area at 1310 nm. Moreover, in the suspended core, the LP₁₁ mode is easier excited than LP₀₁ mode if the lateral-offset exceeds ~1.4 μm. When the lateral-offset reaches ~6.3 μm, the LP₁₁ mode in suspended core and LP₀₁ mode in the center core can be excited almost equally. To obtain a large fringe visibility of the interference spectrum, the lateral-offset is selected in the range of 6 ~ 8 μm.”
