InAs/InP quantum dot mode-locked lasers grown on (113)B InP substrate

We report for the first time the passive mode-locking of single section Fabry-Perot (FP) lasers based on InAs quantum dots grown on (113)B InP substrate. Devices under study are a 1 and 2 mm long laser diodes emitting around 1.58 μm. Self-starting pulses with repetition rates around 39 and 23 GHz and pulse widths down to 1.5 ps are observed after propagation through a suitable length of single-mode fiber for intracavity dispersion compensation.
