arXiv:2402.17750v2 Announce Type: replace-cross Abstract: Controlled multimode wave propagation can enable more space-efficient photonic processors than architectures based on discrete components connected by single-mode waveguides. Instead of defining discrete elements, one can sculpt the continuous substrate of a photonic processor to perform computations through multimode interference in two dimensions. Here we designed and demonstrated a device with a refractive index that can be rapidly reprogrammed across space, allowing arbitrary control of wave propagation. The device, a two-dimensiona
This development arises from ongoing research into novel computing architectures to overcome the limitations of traditional electronics, driven by increasing demands for processing power in AI.
A strategic reader should care because arbitrary control over multimode wave propagation opens a new paradigm for photonic computing, potentially leading to significantly more powerful and energy-efficient AI hardware.
The ability to dynamically reprogram photonic substrates for computation through multimode interference fundamentally changes how optical processors can be designed, moving away from discrete components to continuous computation.
