On-chip 1 TOPS Hyperdimensional Photonic Tensor Core using a WDM Silicon Photonic Coherent Crossbar
S. Kovaios, I. Roumpos, A. Tsakyridis +4
We demonstrate an on-chip 0.96 TOPS hyperdimensional photonic tensor core by utilizing a time-spacewavelength multiplexed silicon photonic Crossbar (Xbar). The novel architecture r…
All-optical temporal integration mediated by subwavelength heat antennas
Yi Zhang, Nikolaos Farmakidis, Ioannis Roumpos +8
Optical computing systems deliver unrivalled processing speeds for scalar operations. Yet, integrated implementations have been constrained to low-dimensional tensor operations tha…
All-Optical High-speed Programmable Nonlinear Activation Functions using a Fabry-Perot Laser
Mladen BanoviÄ, Petar AtanasijeviÄ, Antonios Prapas +12
The threads of photonics are eagerly awaited to redefine the future of neuromorphic data processing, especially as the computing-intensive artificial intelligence models become an…
A 262 TOPS Hyperdimensional Photonic AI Accelerator powered by a Si3N4 microcomb laser
Christos Pappas, Antonios Prapas, Theodoros Moschos +13
The ever-increasing volume of data has necessitated a new computing paradigm, embodied through Artificial Intelligence (AI) and Large Language Models (LLMs). Digital electronic AI…
