In this paper, we report the experimental results of a

hybrid wideband fiber amplifier. The amplifying medium

is a concatenated hybrid fiber consisting of Er-doped fiber

(EDF) and dispersion compensating fiber (DCF). The gain

mechanisms are based on stimulated emission in the EDF

and stimulated Raman scattering (SRS) in the DCF. Since

we simultaneously use optical amplification by the two

processes, the gain bandwidth is easily expanded over 105

nm by a two-tone pumping scheme. Using an

experimental setup constructed with a hybrid structure of

EDF-DCF-EDF, we analyzed the spectral behavior of

amplified spontaneous emission for pumping powers. We

achieved an optical gain of over 20 dB in the wavelength

range from 1,500 to 1,600 nm under optimized pumping

conditions to make the spectral gain shape flat.
