Hermetic Welding of an Optical Fiber Fabry–Pérot Cavity for a Diaphragm-Based Pressure Sensor Using CO₂ Laser

A diaphragm-based hermetic optical fiber Fabry–Pérot (FP) cavity is proposed and demonstrated for pressure sensing. The FP cavity is hermetically sealed using one-step CO₂ laser welding with a cavity length from 30 to 100 μm. A thin diaphragm is formed by polishing the hermetic FP cavity...
