Abstract

In this paper, split-band Hybrid Waveguide Amplifier (HWA) is proposed using parallel configuration of Er-doped waveguide amplifier (EDWA) and Er-Yb co-doped waveguide amplifier (EYDWA) for C+L-band dense wavelength division multiplexed system at 0.2 nm interval. This HWA plays a role to boost the DWDM signals and giving a larger gain while keeping the little power/gain variations over effective gain bandwidth product. With the proposed amplifier, the gain and power variation is reduced from 7.2 to 3.1 dB without using any costly gain clamping techniques.
