Abstract
Embodiments described herein may be related to apparatuses, processes, and techniques related to fully integrated optical coherent modulators on a silicon chip. These coherent modulators may be used to enable transmitters, receivers, transceivers, tunable lasers and other optical or electro-optical devices to be integrated on a silicon chip. In embodiments, the optical coherent modulators may be based on differential microring modulators that may be nested in a Mach-Zehnder Interferometer (MZI) configuration. Embodiments may also be directed to a miniaturized and fully integrated coherent modulators, which can enable terabit per second (Tbps) transceivers in a small form factor based on coherent modulation on a silicon chip. Other embodiments may be described and/or claimed.
