Modeling and Simulation of Optoelectronic Devices

With the increasing demand for high speed and high efficiency processing (computing), transmission, and reception of information, semiconductor optoelectronic devices are becoming more and more important. Modeling and simulation of such devices are critically important for understanding the device physics and performance limits, and for device and system design. Just as electronic device simulation is critical to today's micro-electronics industry, so will be the optoelectronic device simulation to the future optoelectronic industry. Our projects are outlined as following:

The primary task is to develop accurate and computationally efficient microscopic models of the physical processes that play important roles in determining optoelectronic device performance. These processes include carrier-carrier and carrier-phonon scattering, plasma heating, carrier capture by and escape from quantum wells, and other many-body interaction processes.

We are also interested in combining individual process models into a single simulation tool for optical device simulation. This tool will be used to study the transverse modes and temporal dynamics of vertical cavity surface emitting lasers (VCSEL), to assess the model and simulator accuracy.

The goal of our project is to develop an efficient and comprehensive simulation capability for optical devices (both
active and passive) including optical, electronic, and thermal processes in a self-consistent fashion. Our final goal is to integrate our optical package with electronics package to form a self-consistent tool for the optoelectronic integrated circuits (OEIC). For further details, see my homepage.
