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. Further, the impact of various parameters of EDWA/ EYDWA has been investigated and performance has been evaluated in the term of optical power..
