The Dawn of Energy Efficient Computing: Optically Accelerating the Fast Fourier Transform Core

Not Accessible

Your library or personal account may give you access

Abstract

We present a novel approach in optical processing by accelerating Fourier transform through integration of silicon photonics and free-space optics. We introduce Fourier transform based multiply and accumulate operations, that require less number of operations compared to the traditional multiply and accumulate operations used in computer architecture.
