Ultra-short optical pulses and pulse trains are of considerable importance in many applied science fields such as physics, chemistry and biology because of their excellent spatial and temporal characteristics. The pulse shaping technology which is a part of ultra-short pulse research has drawn more and more attention. The pulse shaping technology based on fiber devices has also been proposed because the fiber devices have many strong points such as low insertion loss, easly integration, and so on. In this paper, we review the progress of pulse shaping technology based on optical fiber devices that is used in ultra-short optical pulse generation, arbitrary wave generation and microwave/millimeter-wave generation.
