Abstract :
A simple and novel sampling technique for optical timedivision multiplexing circuit and packet switched data is proposed using a gain-switched distributed feedback semiconductor laser and lithium niobate modulators. System error rate measurements on a two-channel system multiplexing data at 140 Mbit/s and 50 Mbit/s are given and operating penalties analysed.
