论文摘要
纤维BRAGG光栅（FBG）在传感器和激光设备中具有多种应用。在这项工作中，我们使用FS激光器使用点（PBP）技术制造了FBG。 FBGS光谱特性是通过光栅长度，纤维持有人位置，激光功率和涂层层的变化来探索的。 FS FBG是在小模式场直径纤维上制造的，该直径纤维显示了传输深度至2.5 dB的增强。随着平移阶段速度的变化，观察到中心波长偏移从1520 nm到1568 nm。 FS FBG可以用于高压传感，高温感应和危险环境监测目的。
Fiber bragg gratings (FBG) has wide variety of applications in sensor and laser devices. In this work, we have fabricated FBG using point by point (PbP) technique utilizing fs laser. FBGs spectral characteristics were explored through the variation of grating length, fiber holder position, laser power and coated layer. Fs FBG is fabricated on small mode field diameter fiber which shows enhancement of transmission depth to 2.5 dB. The center wavelength shift is observed from 1520 nm to 1568 nm with the change in translational stage speed. The fs FBGs can be utilized in high pressure sensing, high temperature sensing and hazardous environment monitoring purposes.
