Silicon photonics offer a low-cost platform for large-scale optical systems, and find applications in datacenters, long-haul optical networks, LiDAR, and RF/microwave photonics. RF photonic systems offer interference-tolerant, wideband radio systems in RF and millimeter-wave bands. In this work, fundamental sources of nonlinearity in Silicon photonic MZMs are analyzed and novel techniques are proposed to overcome the limitations in order to design high SFDR silicon photonic optical RF receivers. In the next part of dissertation, integration strategies of silicon photonics and electronics are compared for compact and efficient optical transmitters with CMOS drivers, to be used in coherent intra-data center optical links. A hybrid integrated optical transmitter, based on a 45-nm CMOS driver and a silicon photonic segmented MZM, is designed. Next, A fully integrated optical transmitter based on a novel architecture with a 90-nm CMOS driver is presented.


Navid Hosseinzadeh received the M.Sc. degree in electrical engineering from Sharif University of Technology, Tehran, Iran in 2014. He is currently pursuing a Ph.D. program in electrical and computer engineering at the Department of Electrical and Computer Engineering, University of California, Santa Barbara, CA, an is a member of Prof. Buckwalter group. His research interest includes RF/millimeter-wave IC design in silicon and III-V, and design of silicon photonic integrated circuits.
