We demonstrate numerically that the theoretical maximum sensitivity of a ring-coupled Mach-Zehnder interferometer (MZI) optimized as a sensor is about 30% greater than the optimized sensitivity of a conventional single-bus ring sensor with an identical ring perimeter and loss. The ring-coupled MZI sensor also achieves its greater sensitivity with a 25% lower circulating power, which is useful for the suppression of undesirable nonlinear effects.
我们通过数值模拟证明，优化为传感器的环形耦合马赫-曾德尔干涉仪（MZI）的理论最大灵敏度比具有相同环周长和损耗的传统单总线环形传感器的优化灵敏度高约30%。环形耦合MZI传感器还能在循环功率降低25%的情况下实现更高的灵敏度，这对于抑制不良非线性效应很有用。
