A self-calibration nano-scale sensing transducer using PANDA ring resonator

We propose a new system of self-calibration measurement using a nano-scale sensing transducer, which is known as a PANDA ring resonator type, whereas the sensing unit is combined into the system by mean of one ring, and the other ring is set as a reference signal. We use the method of finite difference time domain (FDTD) via the computer programming called Opti-wave to analyze and simulate. The simulation result has shown that we can use this system for high-precision and self-calibration measurement using a nano-scale sensing transducer, whereas the measurement resolution of 1 nm can be obtained. The recovery and the reciprocal signals can also be formed, which can be used to approach to many advantages of measurements, including the possibility of standardizing measurement accuracy.
