A programmable transversal equalizer for electronic dispersion compensation (EDC) in optical fiber communication systems is developed. Based on the SiGe technology with a cut-off frequency of 80 GHz, the equalizer consists of 6 seriesparallel amplifiers as delay units and 7 Gilbert variable gain amplifiers as taps, which ensure that the equalizer can work at the bit rate of 10 Gb/s. With different...
The influence of temperature and Ga composition on Auger recombination lifetime in n-type and p-type In1−xGaxAs materials is investigated through the simulation, assuming the concentrations of electrons and holes are 1017 cm−3 and 1018 cm−3, respectively. The results show that the temperature has little influence on Auger recombination lifetime of In1−xGaxAs materials at x<0.3. However, it...
