【Abstract】 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.更多还原
