Abstract
The feasibility of constructing a dual-wavelength, spatially single-mode, superfluorescent fiber emitter on the basis of erbium optical fibers with pumping by multimode semiconductor lasers is demonstrated. The emitter is fabricated by all-fiber technology and has a power output in excess of 10 mW, an average emission wavelength of 1.54 μm, and a spectral resolution of 27.5 nm at component linewidths of 3 nm and 9 nm. The depolarization of the radiation from the emitter as it propagates in an anisotropic, single-mode fiber waveguide is investigated.
