Qiu, and Y. Su, “ On-chip silicon photonic 2 × 2 mode- and polarization-selective switch with low inter-modal crosstalk,” Photonics Res. 5, 521 ... WebConventional router microarchitecture for low-radix topologies had a limited number of ports (i.e., 6 to 8 ports) and thus, centralized arbitration could be used. However, arbitration logic is proportional the O (k2) where k is the router radix (number of input and output ports).
