Paper Abstract

Erbium doped optical fibers represent an elegant class of on-line optical amplifier working in the low loss window at 1.5 microns. This paper reports on an experimental study made of an Erbium doped optical fiber amplifier pumped at various wavelengths. The fiber was pumped at different wavelengths using an Argon ion laser, a dye laser and a He-Ne laser. Both contra and codirectional pumping geometries were investigated and further, simultaneous pumping at two different wavelengths with codirectional and contradirectional geometry was studied. The gain was measured as a function of fiber length, input signal strength and input pump powers. These experimental gain characteristics have been studied and analyzed.
