Abstract

We demonstrate the first photonic transposed convolution accelerator using micro-combs, achieving a mean squared error of 0.006 in image reconstruction at trillions of operations per second through customizing dimension amplification in a time-wavelength interleaved system. © Optica Publishing Group 2025.
