Scaling Photonic Tensor Cores with Unary and Homodyne Designs

Published 16 Apr 2026 in physics.optics and cs.AR | (2604.14664v1)

Abstract: We analyze five photonic microring tensor core designs with a common optical power model. The results show that circuit ordering, unary encoding, and homodyne accumulation shape scalability, with the last two offering the strongest path to higher parallelism.
