Mixed-level simulation of opto-electronic devices

Presented here are two important devices that cannot be modeled accurately and/or tractably by a single simulation technique. Simulation flows to address each device are presented. The first is a patterned Light Emitting Diode (LED), the optical modeling of which requires a mixed-level simulation approach combining FDTD (or RCWA) and Ray Tracing. The second is a CMOS Image Sensors (CIS), which requires process, optical and electrical simulation techniques.
