This thesis focuses on the study of novel InAs quantum dot (QDot) and quantum dash
(QDash) structures based lasers grown on InP substrates. It firstly covers device fabrication …

Mode-locked semiconductor lasers are compact pulsed sources with ultra-narrow pulse
widths and high repetition-rates. In order to use these sources in real applications, their …

This paper reports recent results on InAs/InP quantum dash–based, two-section, passively
mode-locked lasers pulsing at 41 GHz and 10.6 GHz and emitting at 1.59 μm at 20 C. The …

Quantum dash based laser diodes have attracted the focus of study and research in the very

We report, for the first time to our knowledge, on the self-injection locking of chirped InAs/InP
quantum-dash (QDash) lasers with~ 6.5 nm locked Fabry-Perot mode tunability, in the L …

We report optical injection-locking in 21-GHz single-section and two-section InAs/InP 1.5-μm
quantum-dash mode-locked lasers. Two distinct mode-locked regimes were observed and …

Unprecedented high modal gain of~ 100 cm-1 is obtained for an optimized structure based
on InAs/InP quantum dashes (QDash) emitting at 1.55 μm. This structure allows achieving …

The explosion of internet traffic, the increase in data or multimedia transmission are the main
reasons for a huge rise in demand for transmission bandwidth especially in dense …

The static and dynamic properties of state-of-the-art InP-based QDash lasers around 1.55
