Abstract
The bandwidth bottleneck looming for traditional electronic interconnects has driven the consideration
of optical communications technologies as realized through the complementary metal-oxide-semiconductor-compatible
silicon nanophotonic platform. Within the silicon photonics platform, silicon microring resonators have received a
great deal of attention for their ability to implement the critical functionalities of an on-chip optical network
while offering superior energy-efficiency and small footprint characteristics. However, silicon microring-based
structures have a large susceptibility to fabrication errors and changes in temperature. Integrated heaters that
provide local heating of individual microrings offer a method to correct for these effects, but no large-scale
solution has been achieved to automate their tuning process. In this context, we present the use of dithering signals
as a broad method for automatic wavelength tuning and thermal stabilization of microring resonators. We show that this
technique can be manifested in low-speed analog and digital circuitry, lending credence to its ability to be scaled to
a complete photonic interconnection network.
