摘　　要：利用可编程控制装置对光纤光栅的中心波长进行了线性调谐，在此基础上实现了可控波长行波环形腔激光器的运转，波长线性调谐范围可达5．9nm。通过精确控制，波长选择的复现性可达5．13×10-3nm，在检测仪器的精度范围内，波长调谐的线性度达R2=0.999，波长选择间限为0．156nm。A programmable wavelength selective and scanning structure is reported in thispaper, which is used to tune the central wavelength of a fiber Bragg grating linearly. Basedonsuch a structure, an all- fiber traveling- wave ring laser is fabricated. The outputwavelength can be selected with a computer and can also be continuously scanned in a rangeof 5. 9 nm. The linearity is up to R2 = 0. 999, the wavelength-interval is 0.156 nm, andthe wavelength reproducibility is 5.13 ×10-3 nm ) which is within the measuring limit of theoptical spectrum analyzer.
