A Novel Flattened Gain RAMAN-Photonic Crystal Quantum Dot Semiconductor Hybrid Optical Amplifier in U Band for Super Dense Wavelength Division Multiplexing System

Abstract

For the very first time, effect of RAMAN-PCQDSOA hybrid optical amplifier (HOA) in terms of flattened gain with noise figure has explored in this paper for 400x10 Gb/s super dense wavelength division multiplexing (SD-WDM) optical communication system with channel spacing of 100 GHz. Performance of proposed HOA has also compared with RAMAN-RAMAN, EDFA-EDFA and SOA-SOA HOA in terms of same features. Least variation of .05 dB ever recorded from RAMAN-PCQDSOA HOA for the flattened gain (30.1 dB to 18.22 dB) in the range of U-band from 1625 nm to 1675 nm. Further, proposed HOA has also declared to attain maximum gain of 30.1 dB with noise figure (NF) of -2.5 dB.
