Summary

Story summary

Harvard University researchers developed a model to boost parallel optical computing with cascaded Mach-Zehnder interferometers.
They addressed dispersion with a wavelength-dependent transfer matrix framework and validated it experimentally.
The team proposed a computationally efficient error correction strategy that cut global dispersion error from 0.22 to 0.039 over a 40 nm range.
The approach increases computational throughput without extra hardware, enabling reliable multi-wavelength optical processors for artificial intelligence and image processing.
