Patent ID: 7409327

Claim:
A method of operating a computer processor, the computer processor using computer software, the computer software being configured to simulate both the electrical characteristics and the optical characteristics of a silicon-on-insulator an (SOI)-based integrated optical/electronic circuit, the method comprising: a) simulating operation of at least certain electronic circuit components of said SOI-based integrated optical/electronic circuit using an electronic design portion of the computer concentration software to generate as outputs dopant profiles, topology information and free-carrier concentration information and time-dependent variations in the free-carrier concentration as a function of applied voltage; b) applying, the output information from the electronic design portion of the computer software as inputs to an optical design portion of the computer software to extract top-level optical parameters Such as optical loss, optical phase and extinction; and c) simulating both the electrical and optical behavior of said integrated optical/electronic circuit through said electrical and optical computational engines to predict the optical behavior of said SOI-based integrated optical/electronic circuit.
