摘要：

We investigate a fourth-order PT symmetric optical sensor and analyze its eigenfrequency phase diagram. The four eigenfrequencies of our optical sensor simultaneously collapse at the high-order exceptional point in parameter space, providing a quarter root relation between the frequency splitting amount and the perturbation. A clear sensitivity boost is observed when comparing the frequency splitting with other optical sensors under small perturbation condition.
