Error in Figure 2

In the original article [1], there was a mistake in Figure 2 as published. The figure was not shown over the complete range of interest. The corrected Figure 2 appears below. The authors apologize for any inconvenience caused and state that the scientific discussion and conclusions are unaffected. The original article has been updated.

Error in Figure 4

In the original article [1], there was a mistake in Figure 4 as published. The numbers on the right y-axis were missing the last digit. The corrected Figure 4 appears below. The authors apologize for any inconvenience caused and state that the scientific discussion and conclusions are unaffected. The original article has been updated.

Text Correction

There was an error in the original article [1]. The 1/e pulse duration for the simulations in Section 3.1 was listed as 72 fs. However, this is the half duration, and not the full 1/e pulse duration. Thus, a correction to 144 fs was made in the corresponding place in the paper.

A correction was made to Section 2.2, Paragraph 2 (shown in bold letters):

For input, in Section 3.1, a transform-limited Gaussian pulse (1/e power duration, τ, of 144 fs), with a pulse energy of 2 nJ is used. The peak power and duration of this input pulse renders that SCG here is in the SPM-dominated regime of the ND fiber. We find that the typical characteristic spectral phase evolution of the SCG pulse in the SPM-dominated regime is shown with these parameters.
