In Fig. 6 of our recent paper [1], the thickness effects of the whispering-gallery mode (WGM) and surface plasmonic resonance (SPR) integrated ring resonator on the $F$- and $Q$-factors were examined. However, the author (Y. Hao) made a mistake in the calculation of the $F$-factors for the cases when the ring resonator thickness was greater than 1 µm. He mistakenly used the radiation intensity of the pure ring resonator of 1 µm thickness as the denominator to calculate the $F$-factors at various ring resonator thicknesses and thus mistakenly concluded that the enhancement $F$-factor was less than unity when the ring resonator thickness was over 1.3 µm. The $F$-factors are now corrected in Fig. 1 in this erratum, and it is seen that the $F$-factor only slightly decreases with increasing ring thickness and all the $F$-factors in the studied hybrid resonators are greater than 3.2. All other results and conclusions in [1] were not affected by this mistake. In the new figure, we show the values of the $Q$-factor for various scenarios, while in the original figure in [1] the $Q$-factor ratio was shown in comparison with the $Q$-factor value of a pure WGM ring resonator of 1 µm thickness.
