摘要
本文采用数值孔径(N.A)法首次计算了光纤-波导端面的耦合效率和器件的响应特性;全面测试了器件的性能,其理论分析与实验结果符合较好;还讨论了进一步提高器件的探测灵敏度及其实用化的途径.
This paper reports a novel integrated optics microdisplacement sensor which has been fabricated in our Labs, based on S. Honkanen's proposal. The NA approach is firstly used for ca]culating the characteristics of the sensor and all the performances of the device are measured. The theoretical analysis and experimental results are in agreement basically. Several ways to improve the sensitivity of the device are presented. The sensor could be used in a wide area, such as vibration, acceleration and acoustic sensing etc.
