Abstract

Based on mode coupling theory,tilted fiber Bragg grating temperature sensing principle and the characteristics of transmission spectrum of fundamental modes and high-modes are proposed.The temperature shift of fundamental modes resonance wavelength and high-order modes resonance wavelength is investigated by means of simulation method.The tilted angle on the effect of resonance wavelength is discussed.The results show that the different resonance wavelengths are linealy increased with surrounding temperature.The center wavelength of transmission spectrum is non-drift with the increase of tilted angle,and the width of transmission spectrum decreases with the increase of tilted angle.The result has a certain guiding function to the application of the tilted fiber Bragg grating.

倾斜光纤光栅温度传感的传输功率谱研究

基于模式耦合理论，提出了倾斜光纤布拉格光栅的感温原理及基模和高模的透射光谱特性。采用仿真方法研究了基模共振波长和高阶模共振波长的温度变化。讨论了倾斜角度对共振波长的影响。结果表明，不同的共振波长随周围温度呈线性增加。随着倾斜角度的增大，透射光谱的中心波长不漂移，透射光谱的宽度随着倾斜角度的增大而减小。研究结果对倾斜光纤布拉格光栅的应用具有一定的指导作用。

期刊介绍： The predecessor of Optical Technology was Optical Technology, which was founded in 1975. At that time, the Fifth Ministry of Machine Building entrusted the School of Optoelectronics of Beijing Institute of Technology to publish the journal, and it was officially approved by the State Administration of Press, Publication, Radio, Film and Television for external distribution. From 1975 to 1979, the magazine was named Optical Technology, a quarterly with 4 issues per year; from 1980 to the present, the magazine is named Optical Technology, a bimonthly with 6 issues per year, published on the 20th of odd months. The publication policy is: to serve the national economic construction, implement the development of the national economy, serve production and scientific research, and implement the publication policy of "letting a hundred flowers bloom and a hundred schools of thought contend".
