Electro-optic wavelength-tunable fiber ring laser based on cascaded composite Sagnac loop filters.
A continuous wavelength-swept fiber ring laser with a lithium niobate waveguide electro-optic polarization controller in an intracavity fiber Sagnac loop is experimentally demonstrated. Composite fiber Sagnac loop filters are cascaded to demonstrate discrete wavelength switching of a single-wavelength fiber ring laser. Stable single-longitudinal-mode operation is achieved by use of a Sagnac loop saturable-absorber filter.
