Gain-switched pulse generation of 5.3 ps from 30 GHz-modulation-bandwidth 1270 nm DFB laser diode: erratum

We present an erratum to our Letter [Opt. Lett.48, 6344 (2023)10.1364/OL.510237]. This erratum corrects the error of Figs. 3(b) and 4(b) made via incorrect scaling in the horizontal axes. The corrections have no influence on the main text and conclusions of the original Letter.
