研究目的
To present and discuss a new method to amplify the sensitivity based on separated Fabry-perot interferometers (FPI) causing Vernier effect.
研究成果
The new structure to achieve Vernier effect maintains the amplification factor and eliminates the disturbance term in the spectrum, making it easier to fit the envelop curve. This has extensive practical value.
研究不足
The study is based on theoretical simulation and lacks experimental validation. The practical implementation of the proposed structure may face challenges in fabrication and alignment.
1：Experimental Design and Method Selection:
The study involves theoretical analysis and simulation of the spectrum of typical cascaded cavity based on Vernier effect. A novel structure using two separated FPIs is proposed to realize Vernier effect for sensitivity amplification.
2：Sample Selection and Data Sources:
The study uses simulated data based on theoretical models of FPIs.
3：List of Experimental Equipment and Materials:
Optical circulators, FPIs, broadband source (BBS), optical spectrum analyzer (OSA).
4：Experimental Procedures and Operational Workflow:
The light from BBS is input into the first FPI sensor, causing interference spectrum, then reflected beam inputs to the second FPI sensor, causing similar spectrum. The interference light intensity received by OSA is analyzed.
5：Data Analysis Methods:
The reflective spectrum of the cascaded cavity FPI sensor with Vernier effect is calculated and analyzed to observe the elimination of disturbance term and sensitivity amplification.
