Abstract
In this paper, Fabry-Perot laser diode (FP-LD) based pulse generation and its application in optical signal processing is demonstrated. Three topics are focused which including: (i) continuously wavelength-tunable optical short pulse generation in a relatively wide range of 42 nm based on FP-LD by enlarging injection locking range, The sidemode suppression ratio achieved is 35 dB over the whole wavelength tuning range; (ii) a simple method to generate high power and 139 GHz high repetition rate pulse train based on self injection-locking in a commercially available FP-LD; (iii) a novel, simple, and low cost method for all optical clock recovery at 10 GHz based on the switching of two longitudinal modes in a dc biased multi-quantum-well (MQW) FP-LD.
