Abstract :
Recently, high-frequency 1.3μm InGaAsP constricted mesa lasers have shown a small-signal -3 dB bandwidth of more than 15 GHz at 15°C, and have been modulated with pseudorandom pulses at 8 Gbit/s (NRZ format). The letter reports large-signal digital modulation of such a constricted mesa laser using time-multiplexed electrical pulses 80 Ps in duration and 125 Ps apart which demonstrates the high-speed modulation capability of this laser at a simulated bit rate of 16 Gbit/s (NRZ).
