Abstract
Rotary optical switching enables low-loss microsecond-scale reconfiguration between pre-programmed interconnects with thousands of ports, supporting high-bandwidth and low-latency Rotornet datacenter architectures. We describe a 7 µs 128 × 128 port rotor switch with 4 dB fiber-to-fiber insertion loss and a 1-dB spectral bandwidth of 120 nm.
