| 研究開始時の研究の概要 |
Photonic Networks-on-Chips (PNoCs) are promising technique, which utilizes the transmission of photons across a waveguide to transmit the data. PNoCs offer several benefits over conventional electrical NoCs, such as high-bandwidth support, distance independent power consumption, lower latency, and improved performance-per-watt. The photonic domain is immune to transient faults caused by radiation but is still susceptible to process variation (PV) and thermal variation (TV) as well as aging. This research focuses the reliability of PNoCs for nano-photonic circuitry.

| 研究実績の概要 |
The Photonic Networks-on-Chip has been studied especially on reliable routing algorithm. Photonic Networks-on-Chip are inherently more resilient to alpha particles because of using photons for communication but suffer from other forms of faults such as thermal variation. In order to control faults by the thermal variation, the microring resonators are fabricated with a flattened coil that can heat up the microring resonators. The strain-based calculation can be improved by improving both sub aspects of the algorithm. Instead of using a threshold of failed microring resonators, a performance factor is calculated based on every possible combinations of failed microring resonators in the individual switch. This way, there is no guessing whether a message can make it through the switch if two microring resonators in the same location have failed. The second point of improvement is to skip the power-based temperature estimation and replace it by separating the network into segments of single nodes and measuring the temperature of each segment. The resulting publication is almost ready for submission. In the future, the control method might be applied to advanced network such as satellite networks.
