ABSTRACT
This research presents a new method for generation of multilevel pulse amplitude modulation (PAM-4) signals for optical interconnects and data center networks. The new approach uses multimode interference (MMI) structure with two phase shifters in push-pull configuration instead of microring resonators and two couplers as shown in the literature. Based on this structure, an extreme high bandwidth and compact footprint can be achieved. The whole device is designed and analyzed using the existing VLSI silicon photonics.
