Author Correction: Nanophotonic optical gyroscope with reciprocal sensitivity enhancement

In the version of this Letter originally published, in equation (1), ‘ n ’ should not have been included. Accordingly, in the sentence following equation (1), the definition “ n is the refractive index of the medium” should not have been included. In addition, the authors should have declared the following competing interest: “P.P.K. and A.H. have filed a patent application (Integrated optical gyroscope with noise cancellation, US patent application US 15/993,525; 13 December 2018).” These corrections have been made in the online versions.
