高环境适应性可调谐激光源
High environment adaptability tunable laser source
摘要
Abstract
To meet the application requirements of tunable laser sources for optical frequency-domain re-flectometry(OFDR),a wide-tuning-range,mode-hopping-free semiconductor tunable laser source with high environmental adaptability is designed.Based on the theory of synchronous variation of feedback light and cavity modes,the pivot point is calculated and analyzed to achieve optimal mode matching between the oscillating light in the internal cavity and the external cavity during the tuning process.Subsequently,the output characteristics of the tunable laser source,including wavelength stability and power fluctuation under various conditions such as high and low temperatures and mechanical vibration,are experimentally investigated.The results demonstrate that the tunable laser source operates stably over long durations within an ambient temperature range of 0 ℃ to 40 ℃ and under conditions of drop and mechanical shock.At a driving current of 400 mA,continuous,mode-hopping-free tuning from 1 499.999 8 nm to 1 649.999 6 nm is achieved;the power fluctuation over the entire tuning range is better than 0.033 1%,the wavelength stability is better than 0.33 pm over 1 h,and the absolute wavelength accuracy is better than±0.85 pm.These performance metrics essentially meet the application requirements of high-preci-sion optical link sensing OFDR systems.关键词
