Abstract

We incorrectly calculated and marked the whispering-gallery-mode (WGM) order of the ring cavity in our manuscript. Here, we provide the correct value of WGM orders. It should be mentioned that the main results, techniques, and conclusions presented in the published paper would not be affected.

In section 2&3 of our manuscript [1], we incorrectly calculated and marked the whispering-gallery-mode (WGM) order of the ring cavity. In [1], the WGM order is obtained from electric intensity distribution (|E|2) along the ring. However, the WGM order represents the cycle number of electric field distribution along the ring so that it should be calculated from the amplitude field distribution (E). Here the correct WGM orders are summarized as:

Resonantfrequency IncorrectWGM order CorrectWGM order OAM order
192.56 THz365181−3
193.26 THz366182−2
193.98 THz367183−1
194.68 THz 368 184 0
195.41 THz3691851
196.11 THz3701862
196.82 THz3711873
197.53 THz3721884

The authors regret the errors, although these do not change the techniques and conclusions presented in [1].
