In this paper, 40-Gb/s all-optical 3R regeneration has been experimentally demonstrated based on semiconductor devices. The 3R regenerator incorporates an amplified feedback laser (AFL) for all-clock recovery and a semiconductor optical amplifier delayed interferometer as the optical decision gate. 40-GHz optical clock with low timing jitter and uniform amplitude is successfully recovered from the...
A simple and feasible techniques for ultra-wideband (UWB) triplet pulse generation based on gain switching of self-seeded reflective semiconductor optical amplifier (RSOA) is proposed and demonstrated. The proposed system consisted of RSOA, erbium doped fiber laser (EDFA), two fiber Bragg gratings (FBGs), and balanced photo detector (BPD). The short pulse train which has a low timing jitters and pulse...
In this paper, we will put in perspective the Raman amplification challenges for next generation networks and review the physical principles and theory associated to this amplification technique.
The investigation of a radio-over-fibre distribution system with optical pre-distortion feedback linearization of semiconductor optical amplifier (SOA) for communication systems has been proposed. The simulation verified OPDFB linearization for two tones CW indirect modulation to optical fibre. This technique has investigated linearization for the SOA amplifier by an OPDFB linearizer to cancel out...
