Physical simulation of light sources for integrated photonics

The objective of this proposed project is to develop a prototype numerical simulation software that can simulate the physical processes inside semiconductor lasers and exchange information with a simplified compact model. The combination of these two models can better balance the trade-off between accuracy and simulation performance. The resulting integration will be suitable for studying issues arising from the integration of semiconductor lasers in photonic integrated circuits with 1000s of elements, which is a critical challenge for the next generation of optical communications devices.

Multiphysics Simulation of Optoelectronic Devices, Circuits and Systems

Traditionally, the microchips that power our communications technology use electrical signals to compute, transfer, and store information. Silicon photonics (SiP) is an emerging field, where structures fabricated on those same microchips replace electrical signals with optical ones, enabling exciting new applications such as optical and wireless communications, bio/environment-sensing, and computing.

Integration of INTERCONNECT and Cadence with an emphasis on co-simulation of CMOS drivers and optical ring modulators

The idea of using light for transferring data has been developed rapidly since 1960s. Today, using light for short-distance communication, as an alternative for copper wires, is rapidly growing mostly because of its broadband communication characteristics. Optical communication systems consist of both electronic and photonic components. Designing such systems will benefit from an Integrated Development Environment (IDE) to not only simulate both electrical and optical designs but also co-simulate electro-optical subsystem efficiently and accurately.

Process Modeling for Ge-on-Si Photodetectors

High-performance Ge-on-Si photodetectors are of lower cost and can be monolithically integrated with Si based integrated circuits for on-chip optical communications to increase computing speed. Process modeling is essential for structure and processing conditions design, but the current photonic design tools are too simplified for this task. This research is to implement process models in a photonic device design tool Lumerical DEVICETM. Focuses will be given on the Ge and dopant distributions at Si/Ge interfaces.
