“…Qualitatively, this model shows good agreement with the real laser and can be used to find the optimum modulation condition in the gigabit per second range. The optimization is performed by finding the proper pulse current that after each pulse makes the density of excited electrons return as fast as possible to steady state, thereby, obtaining minimum pulse interaction [8], [12].…”

The system includes an HP 21 MX minicomputer with a 32K main memory and a disk, making it possible to handle easily 4096 data points in both the time and the frequency domains. The modular organization of the software and the command file control of the processing have created a flexible system that has proved to be useful in evaluating models of semiconductor lasers and avalanche photodiodes. Furthermore, the system has been used to develop modulation methods for semiconductor lasers in the gigabit per second range.

“…Gain switching semiconductor lasers is one technique that can be used to generate short, periodic pulses [1,2]. Several schemes for achieving pattern independence have been previously demonstrated [4,[6][7][8]. Pattern dependence can be eliminated by using a suitable modulation current waveform that ensures that the carrier density is the same at the beginning of each bit period, independent of the bit sequence [3][4][5].…”

A simple scheme for data transmission by direct modulation of a gain-switched semiconductor laser is demonstrated. Experimental results are presented that show low error rate and low pattern dependence. The sensitivity of the error rate to changes in drive conditions is also measured. Comparison of our direct modulation scheme with external modulation of the same gain-switched laser shows nearly penalty-free operation.
