Paper Abstract

We propose a novel reconfigurable erbium doped fiber amplifier (EDFA) design for high performance optical pre-amplifier applications. A fiber Bragg grating (FBG) with high reflection at a specific single channel wavelength and two circulator are used in the EDFA design to realize higher gain and optical signal-to-noise ratio (OSNR). This proposed system was compared with conventional co- and counter propagating EDFA normally used as pre-amplifiers. The selected channel amplification was in the C-band. A maximum gain of 38dB with a gain improvement of 10.8dB was achieved at input signal level of - 40dBm at 1550 nm. An OSNR improvement of 12.6dB was achieved as compared to the other two designs. An average noise figure of 5.6dB was obtained and with the appropriate selection of FBG, the design can be configured as a pre-amplifier for any channel within the C-band. The experimental results were compared and agreed with modeling results of the system.
