European Project
„Neuromorphic Polariton Accelerator”

Grant HORIZON-EIC-2023-PATHFINDEROPEN-01

Project Description

MBE Laboratory will collaborate with Warsaw University on the Horizon Europe Pathfinder project “Neuromorphic Polariton Accelerator”, acronym: PolArt. The goal of the project, leaded by prof. Barbara Piętka, is to demonstrate a new way to build artificial intelligence-dedicated circuits using polariton neural networks as optical accelerators. Prof. Czesław Skierbiszewski team will be focused on the design, fabrication and integration of the micro-LEDs and their arrays, that are the key elements to inject and modulate the signal in the waveguides.

Project Goal

The project aims to build a network that performs binary operations based on polariton microcavities. The basic element that enables effective binary operations are semiconductor microcavities. Strong coupling of the microcavity modes with excitons result in gigantic nonlinearities that are required for efficient calculations. The fact that polaritons operating room temperature was recently demonstrated, promises to have a real impact on the technologies of the future. Research units involved in the project have recently shown that this state of matter is extremely interesting in terms of speed and efficiency when used to implement artificial neural networks. Thanks to this new concept device, complex applications related to neural-like processing, will be efficiently implemented, therefore enabling neuromorphic computation to be done in small devices that cannot rely on remote, large bandwidth connection. This proposal benefits from the contribution of several complementary partners coming from many different research areas (material science, physics, optics, chemistry, genetics) and industrial participants that assure the interdisciplinarity and technological oriented target.
