  1. Throughput was calculated using the total write time reported for each connection. If total write time was not reported, then fabrication write speed, number of exposure passes, and connection length were used to calculate total write time
  2. BW bandwidth, / not reported
  3. aEvanescent coupler only
  4. bMirror coupler only
  5. cEstimated based on SiN to ULI measured coupling loss
