Challenges and progress toward a silicon-based multi-microring optical network-on-chip
Data di pubblicazione: 23 Giu 2014
This paper presents an integrable optical network-on-chip based on multiple microrings, named multimicroring (MMR). The network consists of a central resonating microring with local microrings connected to the input/output ports. Multiple parallel communications can be supported through wavelength division multiplexing by properly tuning local microrings. The paper reports progress towards the realization and control of the MMR network-on-chip using a silicon-based CMOS compatible platform. Strained silicon is selected and demonstrated to be a valid material for realizing integrated devices suitable for packet switching. Then a mathematical model based on the transfer matrix method is used to assess the MMR physical performance, showing that the network is robust to crosstalk. Finally a novel scheduling framework is proposed for arbitrating the packet transmissions. Simulation results of the network …
