Abstract

The performance of wide-band indium gallium arsenide (InGaAs) quantum dot lasers operated in a passively q-switched mode via the use of saturable absorber sections was investigated. At room temperatures the lasers exhibit multi-mode, self sustained pulsation and its frequency increases with the injection current up to a maximum value of 1.2 GHz. Its oscillation is synchronous across the spectrum and there are power fluctuations between the longitudinal modes which indicates that the dot ensemble behaves as a coupled systems.
