Description

Next generations of large data-centers and supercomputers are lagging due to the stagnation of interconnects speed. Silicon-photonics has been proposed as a potential solution to achieve low-cost, high-speed, and energy-efficient optical links in silicon-based processes. This work presents an optical digital-to-analog converter based on a segmented, active microring resonator in a zero-change commercial 45nm SOI CMOS process. Using this design approach, a monolithically integrated 40Gb/s PAM4 transmitter is demonstrated with 42fJ/b modulator and driver energy and 0.67Tb/s/mm2 bandwidth density. This scheme is suitable for systems-on-chips with large number of I/O links such as processors and switches in large-scale computing and storage systems.
