Abstract
A simple scalable reconfigurable optical add/drop multiplexer was developed for neural application computing in mega datacenters (DCs). Operations are simplified significantly using a new routing algorithm, while maintaining the contention-free nature. It can accommodate 4096 ports for future DCs.
