Flexible transmitter employing Silicon-segmented Mach–zehnder modulator with 32-nm CMOS distributed driver

Artículo científicoWe propose a flexible optical transmitter for shortreach optical interconnects that includes a silicon photonic segmented Mach-Zehnder modulator (MZM) driven by a distributed six-channel 32nm SOI CMOS driver integrated circuit. Optical equalization is demonstrated to extend the bandwidth limitation of the transmitter with NRZ signaling at 25Gb/s. We also generate four-level pulse amplitude modulation (PAM-4) signaling using the same transmitter architecture. Transmission of 46Gb/s PAM-4 signal with bit error rate (BER) well below hard-decision forward error correction limit (BER=3.8×10-3) is experimentally demonstrated. Low driver power consumption of 130 mW at 46Gb/s PAM-4, corresponding to 2.8 pJ/bit power efficiency, is also achieved

Four-channel WDM transmitter with heterogeneously integrated III-V/Si photonics and low power 32 nm CMOS drivers

Artículo científicoWe experimentally demonstrate a novel four-channel wavelength division multiplexing transmitter operating at 1.3 μm wavelength employing heterogeneously integrated III-V/Si photonic circuit copackaged with low-power 32-nm SOI CMOS driver integrated circuits (ICs). Error-free operation (BER < 10−12 ) has been achieved across all four channels for back-to-back, 2 and 10 km single-mode fiber transmission at 25 Gb/s per each channel, targeting intra- and inter-datacenter interconnect applications. Power consumption as low as 19.2 mW for four CMOS driver ICs has been recorded, which yields 0.19 pJ/bit energy efficiency
