A uniform fiber Bragg grating sensor is sketched and inspected by the finite-difference time-domain method in furtherance of obtaining ultimate transmission and reflection spectra by optimizing the FBG parameters like refractive index, grating height, grating width, wafer width, wafer length. The maximum transmission power spectrum is achieved as − 7 dB for the refractive index of 3.005, and the maximum reflection spectra are obtained as 6 dB for the grating height of 1 μm which is enhanced nine times than the precedent work. The proposed FBG is a simple, light-weight, low-cost uniform structure, and it offers high reflectivity and ease of handling. Therefore, it is highly useful in sensing and communication applications.

用于传感和通信应用的统一FBG结构的分析和优化

通过有限差分时域法绘制并检查均匀光纤布拉格光栅传感器，以通过优化FBG参数（例如折射率，光栅高度，光栅宽度，晶片宽度，晶片长度）来获得最终的透射和反射光谱。对于3.005的折射率，最大发射光谱为-7 dB，对于1μm的光栅高度，最大反射光谱为6 dB，这比以前的工作提高了九倍。所提出的FBG是一种简单，轻便，低成本的均匀结构，具有高反射率和易于处理的特点。因此，它在传感和通信应用中非常有用。
