40 Gbit/s data routing through scalable 2D matrix of higher-order ring resonator switches

The first 40 Gbit/s multipath data routing is demonstrated in a two-dimensional switch matrix composed of high-order resonant optical switches. Broadband connectivity with on-state bandwidths exceeding 100 GHz, chip losses below 9.0 dB and signal extinction above 20 dB is achieved through the four paths on the diagonal of the 4 ?? 4 matrix. 40 Gbit/s data routing is demonstrated through three of these paths with power penalties below 0.5 dB for each path.
