Modeling photonic links in Verilog-A

Thesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (pages 59-60).Integrated photonic links are a promising emerging technology that can relieve the interconnect bottleneck in core-to-core and core-to-memory communications of modern processors. Developing and optimizing photonic link systems requires simulation of integrated photonic devices side-by-side with electronic devices at the device, circuit, and system level. In previous efforts to simulate photonic links, the optical and the electrical signals were treated in separate simulators, which resulted in some loss of accuracy. In this thesis, a library of photonic device models is developed in Verilog-A for use in seamless simulation of opto-electronic circuits in Cadence.by Ekaterina Kononov.M. Eng

Robust simulation of opto-electronic systems by alternating complex envelope representations

The increased use of optics in information processing and transmission systems motivates the development of self-consistent opto-electronic transient simulators. This letter presents a technique to significantly improve the DC and transient convergence behavior of a modified nodal analysis based optoelectronic simulation framework by allowing optical device models to be switched between a linear formulation using real and imaginary fields to a non-linear magnitude and phase representation. Configurable multilayer filters and optical ring modulators are used as examples to demonstrate the effectiveness of this approach in obtaining robust simulation convergence
