Sub-Nanometer Displacement Sensor Based on Coupling of Balanced Loss and Gain Cavities

Abstract Sub-nanometer displacement measurement is still a challenge in the current sensor field. In this study, a new type of displacement sensor is designed which is based on the coupling effect of two balanced gain and loss resonators. The optical properties of the sensor have been studied throug...
