“…The utse of optical pre-compensation (OPC) avoids quantization noise, but sees some signal content already suppressed by the transmitter. Splitting the pre-compensation across digital and optical may enable better performance [3]. This allows us to use just enough DPC to avoid the transmitter severely cutting off the signal to avoid significant reduction of the RF swing.…”

“…The exponential growth of global data traffic to meet the demand of cloud computing, mobile Internet, Internet of things, and artificial intelligence, drives optical networks towards a single line rate of 400G-1Tb and beyond. Recently, single carrier transmissions with data rates from 400G to 1Tb have been demonstrated either using electrical time domain multiplexing (ETDM) or a single digital-to-analog converter (DAC) [1][2][3]. In [3], a record rate of single carrier 1 Tb/s transmission was demonstrated by 100 Gbaud 64QAM (quadrature amplitude modulation) using a single LiNbO 3 modulator and a BiCMOS DAC.…”

“…While the combination of the electrical and optical equalization has been previously used in coherent transmission, the digital and optical filters were conventionally treated independently. In [3], the applied digital pre-compensation filter is obtained by calibrating an electrical B2B system, then an optical filter is applied to take care of the remaining frequency slope. However, this digital-first method does not explore the overall joint E/O optimization.…”

We establish experimentally the suitability of an all-silicon optical modulator to support future ultra-high-capacity coherent optical transmission links beyond 400 Gb/s. We present single-carrier data transmission from 400 Gb/s to 600 Gb/s using an all-silicon IQ modulator produced with a generic foundry process. The operating point of the silicon photonic transmitter is carefully optimized to find the best efficiency bandwidth trade-off. We present a methodology to split pre-compensation between digital and optical stages. For the 400 Gb/s transmission, we achieved 60 Gbaud dual-polarization (DP)-16QAM, reaching a distance of 1,520 km. Transmission of 500 Gb/s was further tested using 75 Gbaud 16QAM and 60 Gbaud 32QAM, reaching 1,120 km and 480 km, respectively. We finally demonstrated 72 Gbaud DP-32QAM (720 Gb/s) transmitted over 160 km and 84 Gbaud DP-16QAM (672 Gb/s) transmitted over 720 km, meeting the threshold for 20% forward error correction overhead and achieving net rates of 600 Gb/s and 576 Gb/s, respectively. To the best of our knowledge, these are the highest baud-rate coherent transmission results achieved using an all-silicon IQ modulator. We have demonstrated that we can reap the myriad advantages of SiP integration for transmission at extreme bit rates.

“…IQ-modulators encode information on both real and imaginary parts of the optical carrier by utilizing two nested Mach-Zehnder modulators (MZMs). Well-established technologies rely on LiNbO3, InP, or the Silicon-Organic-Hybrid (SOH) platform [3][4][5] . However, devices based on these technologies end up with relatively large footprints (>0.5 mm long active section).…”
