The Constraints on Quantum-Dot Semiconductor Optical Amplifiers for Multichannel Amplification
IEEE Photonics Technology Letters（2006）
摘要
We report our theoretical studies on the application of InGaAs-GaAs quantum-dot (QD) semiconductor optical amplifier as a single-device multichannel amplifier in the coarse wavelength-division-multiplexing network. Our numerical model exploits the broadened excited states in the QDs to enhance the broadband property of the inhomogeneous QD material
