Abstract :
Optical time multiplexing has been demonstrated using ultrashort optical pulses (30 ps) generated by direct modulation of TJS GaAlAs lasers. With the detection method used, an intensity correlator using second-harmonic generation in LiIO3, a bit rate of 20 Gbit/s was observed. However, the ultrashort optical pulses generated by the TJS lasers indicate that optical time multiplexing at 30 Gbit/s can be achieved.
