Abstract (englisch):
We demonstrate 100 GBd operation of an optical transmitter module including a distributed feedback laser
monolithically integrated with a Mach-Zehnder modulator (DFB-MZM), to the best of our knowledge for the first time. Combining high-speed optics and electronics with digital signal processing (DSP), different schemes for intensity modulation and direct detection (IMDD) at 100, 200 and 300 Gbit/s are analyzed, using electrical signals from a 100 GS a/s BiCMOS DAC. Due to close-to-zero transmitter chirp, 100 Gbit/s NRZ transmission over
1.8 km and 200 Gbit/s PAM4 transmission over 1.2 km at 1550 nm with a bit error rate (BER) below the 7 % overhead forward error correction (FEC) threshold (3.8·10−3) is achieved. At 200 Gbit/s PAM4, the DFB-MZM module consumes only 0.85 pJ/bit, making it a promising device for attractive dual-lane 400 Gbit/s systems. We also achieve 300 Gbit/s PAM8 transmission over 1.2 km with a BER below the 20 % overhead FEC threshold (1.9·10−2) by implementing advanced digi ... mehr
