Abstract

This erratum corrects typos that appeared in Photon. Res. 8, 127 (2020) [CrossRef] in the text, a figure showing the experimental setup, and a table listing the absorption and emission cross section values used in simulations.

The authors wish to correct some typos in Ref. [1]. The corrections are as follows.

1. On page 128, paragraph 3 the word “non-negligible,” should instead just be “negligible.”
2. In Fig. 2(a) of the optical measurement setup a pump diode was incorrectly labeled to be a 1480 nm wavelength, instead of the correct 1470 nm wavelength. Mentions in the text used the correct 1470 nm wavelength value.
3. On page 131 the reference to Fig. 2(a) for the erbium absorption cross section should instead be a reference to Fig. 3(a).
4. The emission and absorption cross section values given in Table 1 and in the text on page 131 were given on the order of $10^{- 20} {cm}^{2}$ , as opposed to $10^{- 21} {cm}^{2}$ . The correct $10^{- 21} {cm}^{2}$ values were used in the simulations.
