Abstract

The current trend in silicon photonics towards higher levels of integration as well as the model of using CMOS foundries for fabrication are leading to a need for standardization of substrate parameters and fabrication processes. In particular, for several established research and development foundries that grant general access, silicon-on-insulator wafers with a silicon thickness of 220nm have become the standard substrate for which devices and circuits have to be designed. In this study we investigate the role of silicon device layer thickness in design optimization of various components that need to be integrated in a typical optical transceiver, including both passive ones for routing, wavelength selection, and light coupling as well as active ones such as monolithic modulators and on-chip lasers produced by hybrid integration. We find that in all devices considered there is an advantage in using a silicon thickness larger than 220nm, either for improved performance or for simplified fabrication processes and relaxed tolerances.
