High-speed thermally tuned electro-optical logic gates based on micro-ring resonators

This work proposes electro-optical design of logic gates using micro-ring resonators (MRR). We achieve this through various combinations of MRRs. In order to modulate the rings, thermo-optic effect is utilized. The reported devices are completely CMOS-compatible and can be fabricated using existing technologies. We also provide static responses to explain the device working principles. By plotting dynamic response spectra, the performance of each device is examined. The proposed logic elements are able to operate at 0.4 Mbps.
