可编程波长选择与扫描全光纤行波环形腔激光器

A programmable wavelength selective and scanning structure was used to tune the central wavelength of a fiber Bragg grating linearly. On this basis, an all-fiber traveling-wave ring laser was fabricated. The output wavelength can be selected with a computer and can be continuously scanned in a range of 5.9 nm. The linearity is up to R²=0.999, the wavelength-interval is 0.156 nm, and the wavelength reproducibility is 5.13 ×10^-3 nm, which is within the measuring limit of the optical spectrum analyzer.
