We present an erratum to correct inadvertent typographical errors in our paper [Adv. Opt. Photon. 7, 168 (2015) [CrossRef] ] and to update Fig. 7 therein following a revised version from the original authors.

Figure 7 in our article [1] was reprinted from the supplementary material of [2]. The original authors of this article, however, issued a subsequent erratum [3] in which this figure was corrected. More recently, further modifications have been made to the original figure regarding the origin of the limiting noise source on the mode shift modality [4]. The updated version of the figure is shown here in Fig. 1, whereby it can be seen that the analysis of Shao et al. shows that for a mode of given , the mode-broadening detection modality can outperform both mode shift and mode-splitting type schemes, but does not necessarily do so.

Additionally, we have found some inadvertent typographical errors. Specifically, we note that by virtue of the definition of the polarizability in Eq. (7), a factor of is missing from Eqs. (6) and (9), which should read
and respectively, where and denote the relative electric permittivity of the particle and host medium and denotes the relative permittivity distribution before any perturbation. All other quantities are as defined in the original article. The factor of should also be dropped from Eq. (10).References
