Parity-time(PT)and quasi-anti-parity-time(quasi-APT)symmetric optical gyroscopes have been proposed recently which enhance Sagnac frequency splitting.However,the operation of gyroscopes at the exceptional point(EP)is chal-lenging due to strict fabrication requirements and experimental uncertainties.We propose a new quasi-APT-symmetric micro-optical gyroscope which can be operated at the EP by easily shifting the Kerr nonlinearity.A single resonator is used as the core sensitive component of the quasi-APT-symmetric optical gyroscope to reduce the size,overcome the strict structural requirements and detect small rotation rates.Moreover,the proposed scheme also has an easy readout method for the frequency splitting.As a result,the device achieves a frequency splitting 105 times higher than that of a classical resonant optical gyroscope with the Earth's rotation.This proposal paves the way for a new and valuable method for the engineering of micro-optical gyroscopes.
