We report the demonstration of a polarized superfluorescent fiber source (SFS) that increases the power output in the desired Linearly polarized component by a factor of 1.76 over that of a standard, unpolarized SFS that uses the same pump power. This increase in efficiency is accomplished by insertion of a low-loss polarizer at an optimum point in the erbium-doped Fiber of a standard SFS. (C) 1997 Optical Society of America
