Abstract

We proposed a new readout scheme for an ultrasensitive gyroscope, which uses the physics of the exceptional points of a PT-symmetric system to enhance the device sensitivity. In particular, we demonstrated that the full-width at half-maximum linewidth (ΔωFWHM) of the light exiting the ring resonator system is proportional to the square root of the rotation rate (Ω). Moreover, we designed a PT-symmetric gyroscope, kept at the exceptional point (at rest) with two 100-μm-radius rings, obtaining a theoretical ΔωFWHMof 3.37×104rad/s for an angular velocity of 100 °/h. One algorithm capable to keep the system at the exceptional point and another one to identify the direction of rotation are also proposed.
