Develop equivalent circuit-based compact models for Si photonic modulators for fast multi-physics simulation.
The simulation of Si photonic modulators typically requires a multi-physics approach. These devices interact with light (FDTD simulation), electric signals (Ohmic/drift-diffusion simulation) and local changes in temperature and/or mechanical stress (finite element simulation). Hence, it is difficult to account for all physical effects simultaneously. In order to have an accurate behavioural model for the purpose of circuit simulation, a compact representation of the device is needed. Compact in this context means that instead of computing the full 3D field property (e.g. temperature or electric field), a single value is computed that is representative for the state of the device.
The objective of this research topic is to develop dynamic, electro-thermo-optic compact models of a Si photonic ring modulator or a Si photonic electro-absorption modulator (depending on the state of research at the start of the internship). Typical steps are:
The projected outcome is to have a validated, multi-physics device compact model. This model will be used to study operational limits and possible design improvements.
