We correct the errors made in the field-overlap derivation in Appendix A of J. Opt. Soc. Am. B 33, 1044 (2016) [CrossRef] .

In our previously published paper [1], we derive an analytical expression of the field-overlap of a Gaussian beam with a simplified surface plasmon field in Appendix A. Equations (A7), (A9), and (A16) have minor errors of factors of 2. Equation (A7) should read

F (l_{G}, w) = {(\frac{2}{π})}^{\frac{1}{4}} \frac{\sqrt{π γ w}}{2} \exp [{(\frac{γ w}{4})}^{2} - 2 γ l_{G}] \times erfc (\frac{γ w}{4} - \frac{2 l_{G}}{w}),

where the arguments of the exponential and complementary error function are corrected. Equation (A9) should read

ζ = \frac{γ w}{4},

and Eq. (A16) is now

l_{G} γ = \frac{1}{2} .

The main result of the field-overlap derivation, given by Eq. (A18), is expressed correctly in the original paper [1]. The analysis and conclusions which use the derivation are thus unaffected by the corrections.
