An ultra-broadband 6 bit digital-to-analogue converter (DAC) has been designed and fabricated in InP-HBT technology. The DAC IC includes six 2:1 MUXs and thus operates with a half-rate clock. The DAC module is equipped with 1 mm connectors for its analogue output to ensure broadband characteristics. The measured analogue output bandwidth (BW) is >40 GHz. Four-level pulse amplitude modulation signals...
A resonating segmented Mach–Zehnder modulator with peaking transfer function is designed and fabricated in InP. The modulator is able to transmit a 56 Gbit/s on–off keying signal although the driver is limited to 20 GHz bandwidth. Bit error ratio over dispersion and optical signal-to-noise ratio are measured and show substantial advantage over their non-resonating counterparts.
