23 and 39 GHz low phase noise monosection InAs/InP (113)B quantum dots mode-locked lasers.

ABSTRACT

Here we report for the first time a passive mode-locking of single section Fabry-Perot (FP) lasers based on InAs quantum dots(QDs) 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 23 and 39 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. A RF spectral width as low as 20 kHz has been obtained leading to a low timing jitter RMS.
