Accurate Infinite-Order Crosstalk Calculation for Optical Networks-on-Chip

Optical Networks-on-Chip (ONoCs) are becoming more and more appealing due to rising network requirements in integrated circuits. One important aspect in ONoC design is the amount of crosstalk generated by the network because crosstalk and Signal-to-Noise Ratio (SNR) are strong limiting factors to network scale and performance. Calculation of crosstalk is thus essential for effective ONoC design. Motivated by this fact, we developed a new general linear algebra based method to calculate the steady-state of any system obeying a simple set of rules. We prove that ONoCs follow these rules and show how this general method can be applied in the particular case of ONoCs to calculate accurate first-order and infinite-order crosstalk and SNR results for any ONoC network.
