A 30 Gb/s CMOS driver integrated with silicon photonics MZM

Abstract: Abstract-A voltage mode modulator driver is proposed in the TSMC 65nm low power CMOS process. In the electrical testing, the driver itself can achieve a bit rate of 40Gb/s with the single-ended output swing of 1.65V. Unlike equivalent CML modulator drivers, when the proposed driver is integrated with the silicon photonic MZM, it does not require an additional biasing network. The integrated electro-optic transmitter can achieve 30Gb/s with an extinction ratio of 4.05dB, with the power consumption of main drive… Show more

“…At the transmitting end of optical communication systems, there are various kinds of modulators to complete electric-to-optical conversion, among which the micro-ring modulator (MRM) is under special consideration. [2][3][4][5] It has a ringstructure PN diode with a waveguide radius of 5-15 μm, and a resistor-based heater to actively adjust MRM working temperature. By applying a different voltage to the two electrodes of the PN junction, MRM output optical power varies linearly with the modulation voltage, which makes it possible for the PAM4 electrical signal to convert into an optical signal.…”

“…In 2015, the University of Southampton reported a 2D integrated optical transmitter achieving 30 Gb/s with the power consumption of main driver being 323 mW. [54] In 2016, a low-cost, smallsize 10 × 11.3 Gbps dense wavelength division multiplexing (DWDM) optical transmitter through 2D integrated SiGe BiC-MOS driver with MZ modulator has been demonstrated. [55] It showed the integration density advantage of heterogeneous integration.…”

“…Differential LE modulators, e.g., sections of segmented MZMs, can also be actuated by current-steering stages. As sketched in Figure 3a, source follower (SF) output stages can be used in this case to present a low output impedance [30]. On the other hand, drivers for single-ended LE phase shifters are traditionally designed by stacking several transistors on top of each other in a CMOS configuration to extend the output voltage swing, as shown in Figure 3b.…”
