Probabilistic photonic computing in symmetry broken Kerr resonators (Invited Paper)

Abstract
In this presentation, we will discuss a novel probabilistic photonic computing platform based on polarization symmetry-breaking in a nonlinear Kerr resonator. Driven by picosecond pulses, the system utilizes a period-2 operating regime to generate symmetry-protected bias-free binary states encoded in intensity, bypassing the need for complex phase stabilization of DOPO-based Ising machines. The platform is highly versatile: without feedback, it functions as a MHz-speed random-number generator; with a DC bias, it produces probabilistic bits with a sigmoidal response; and with measurement-based feedback, it emulates Ising-model dynamics. Experimental results demonstrate its ability to successfully find ground-state configurations for combinatorial problems.

Stéphane obtained his PhD from the Université Libre de Bruxelles (ULB) in 1999. His PhD was concerned with nonlinear optics in passive optical fibre resonators. He then did a post-doc with Prof. John D. Harvey at University of Auckland (New Zealand) working on supercontinuum generation in photonic crystal fibres. In December 2003, he was appointed Lecturer in the Physics Department of University of Auckland, where he has been ever since. He was promoted Professor in 2025. His research has focused on nonlinear optical cavities, both in optical fibres but also in microresonators, studying temporal cavity solitons, optical frequency combs, and more recently spontaneous polarization symmetry breaking and its applications.
