Design of Six-Dimensional System for Efficient Coupling of Fiber and F-P Resonator with High Q Value
The optical sensor based on Fabry-Pérot(F-P)resonator has the advantages of simple structure,high sensitivity and strong anti-electromagnetic interference ability,and has high application value in industry,biomedicine,aerospace and other fields.The input-output fiber structure composed of self-focusing lens,single-mode tail fiber core and lass sleeve and a series of six-dimensional alignment system are designed,which effectively reduces the coupling difficulty of F-P cavity with high Q value and makes the Q value of F-P cavity reach 4.247×107,laying a foundation for the integration and industrial manufacturing of high sensitivity optical sensors.
