Coherent 40 Gb/s SP-16QAM and 80 Gb/s PDM-16QAM in an optimal supercomputer optical switch fabric

We demonstrate, for the first time, the feasibility of using 40 Gb/s SP-16QAM and 80 Gb/s PDM-16QAM in an optimized cell switching supercomputer optical interconnect architecture based on semiconductor optical amplifiers as ON/OFF gates.
