Abstract: PURPOSE: An erbium doped fiber amplifier having a double pass for improving a gain and a noise figure by using a polarization beam splitter and a mirror is provided to improve the gain and the noise figure by amplifying doubly polarized signal light and removing 50 percent of ASE(Amplified Spontaneous Emission) in an amplifying process of the divided polarized signal light. CONSTITUTION: A signal light is divided into two different polarized signal lights by a 4-port polarization beam splitter(2). The divided signal lights travels repeatedly both ends of an erbium doped fiber(6) by a Faraday mirror(7). The divided signal lights are amplified doubly by a pump light of a wavelength division multiplexer(5). Each signal light is rotated as much as 90 degrees. The amplified polarized signal lights are united by the polarization beam splitter(2). In the amplifying process, a noise figure is improved by removing 50 percent of ASE which do not correspond to polarized lights of the polarized signal lights.
