基于腐蚀硼锗共掺光纤的自闭合光纤法-珀传感器
Self-Enclosed Fiber-Optic Fabry-Pérot Sensor Based on Etched B-Ge Co-Doped Optical Fiber
摘要
Abstract
An extrinsic optical fiber Fabry-Perot sensor is fabricated by chemical etching of B-Ge co-doped optical fiber and electrical arc discharge. It is found that the etching rate of the fiber core is more than 30 times foster than that of the standard single-mode fiber when using 40% hydrofluoric acid as etching solution. Within the RI range of 1.350~1.400, the RI sensor has a sensitivity of ~30 dB/RIU and a resolution of~3.33×10-5, with a linearity of >0.99. This low-cost method is suitable for mass production and has great potential for fabricating fiber-optic Fabry-Perot sensors with long cavity lengths for use in spatial-frequency-division-multiplexing.关键词
