【摘要】 对1550nm光纤光栅在应力作用下布喇格波长的偏萨特性进行了实验研究。当纵向拉伸应力加至367．6克时，得到了5．02nm的调谐范围。这可能是在相同应力作用下，目前所报道的最好结果。更多还原

【Abstract】 In this paper,the strain-induced Bragg wavelength shift of fiber gratings was investigated. When a longitudinal stress of 367. 6g was applied to a specially chosen fiber grating, the Bragg wavelength shift up to 5. 02nm has been achieved. In our best knowledge,It would be the largest tuning range under the same stress level.更多还原
