摘　　要：利用简支梁和悬臂梁调谐光纤光栅布喇格波长将造成光纤光栅啁啾。提出了一种新型的纯弯梁调谐方法 ,并进行了理论和实验研究 ,实现了光纤光栅无啁啾调谐 ,用于光纤光栅外腔半导体激光器获得了±It is suggested that the simple beam and the cantilever beam used for tuning FBG will make the FBG chirping. A novel tuning method utilizing the beam under pure bending is introduced. It is proved experimentally and theoretically that this new method will tune the Bragg wavelength without chirp. The FBG external cavity semiconductor laser using this new method has achieved the tuning wavelength of ±1 nm continuously and steadily.
