Paper Abstract

In this paper we report the experimental study of gain of telecommunication Erbium Doped Fiber Amplifier (EDFA). For particular pump power, the gain of Erbium Doped Fiber Amplifier for the wavelength range of 1529 nm - 1559 nm was measured and found that the gain of the Erbium Doped Fiber Amplifier is very uneven exhibiting peaks with different widths around 1532 nm and 1550 nm. On analysis of the results, filters of desired characteristic is suggested which could support for flattening the gain of EDFA for fixed pump power, so that the EDFA could be used for WDM applications. We have flattened the gain spectrum of a commercial Erbium-doped fiber amplifier, obtaining a curve with approximately ± 1.5dB of ripple, from 1530.1 nm to 1556 nm, using five fiber bragg gratings as equalizing optical filter.
