A Recurrent Multiport Interferometer Architecture for Fault-Tolerant Programmable Photonics
Mihai Crisan, David A. Carpenter, Shamsul Arafin · 2024
We propose a novel multiport interferometer architecture that uses optical recursion to mitigate hardware errors and scales as O(N). We also show that it is possible to construct perfect transformations with imperfect beamsplitters meshes.
