Abstract :
The doping and detuning dependences of the threshold, dynamic and spectral properties of multiple-quantum-well distributed feedback lasers were analysed theoretically. It was shown that optimised detuning improves the dynamic and spectral properties. It was also shown that donor doping significantly reduces the threshold current and spectral line-width.
