We demonstrate here a spatially non-blocking optical 4x4 router with a footprint of 0.07 mm(2) for use in future integrated photonic interconnection networks. The device is dynamically switched using thermo-optically tuned silicon microring resonators with a wavelength shift to power ratio of 0.25nm/mW. The design can route four optical inputs to four outputs with individual bandwidths of up to 38.5 GHz. All tested configurations successfully routed a single-wavelength laser and provided a maximum extinction ratio larger than 20 dB.

• Resolving the thermal challenges for silicon microring resonator devices (2014, methodology): “While this configuration is the easiest to implement in fabrication, demonstrated tuning efficiencies are limited, with most results ranging around ~100 mW/FSR [15, 52 – 54], and the best demonstration at ~42 mW/FSR with a tuning speed of 14 μ s [55].”
• Large optical nonlinearity of nanoantennas coupled to an epsilon-near-zero material (2018, background): “Thus, all-optical active devices tend to have large footprints, which limits the integration density to many orders of magnitude smaller than what can be achieved in a state-of-the-art electronic integrated circuits [1, 2].”
• On-chip mode-division multiplexing switch (2015, background): “2(b)] also consists of ring resonators to allow compact, active control by integrated heaters [46].”
