Correction to: Power Flow in Multimode Graded-Index Microstructured Polymer Optical Fibers (Polymers, (2023), 15, 6, (1474), 10.3390/polym15061474)

The authors wish to make three changes to their published paper [1]. There is a mistake in Section 3, on page 4. The value of the maximum principal mode number M was wrong, and the value of the maximum mode number N was missing. The corrected sentence is shown below: The maximum mode number for the GI mPOF under study is N = 580 and the maximum principal mode number is M = N^1/2 = 24 at λ = 633 nm, for g = 2.0, and (Formula presented.) = 0.019711. There is a mistake in Figure 2. The X-axis label should be m/M. The authors added “(the maximum principal mode number is M = 24; the maximum mode number is N = 580)” in the legend for Figure 2. The corrected Figure 2 appears below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
