The Spatial Complexity of Optical Computing and How to Reduce It
Structured sparsity in optical kernels, local sparse for free-space and block-diagonal for photonic chips, reduces the spatial scaling of optical computing from linear to sublinear in the maximum overlapping nonlocality, with modest accuracy loss.
