Solving Distance-Based Optimization Problems Using Optical Hardware
Guangyao Li, Richard Zhipeng Wang, Natalia G. Berloff
We present a practical approach to solving distance-based optimization problems using optical computing hardware. The objective is to minimize an energy function defined as the wei…
Phase Retrieval via Gain-Based Photonic XY-Hamiltonian Optimization
Richard Zhipeng Wang, Guangyao Li, Silvia Gentilini +3
Phase-retrieval from coded diffraction patterns (CDP) is important to X-ray crystallography, diffraction tomography and astronomical imaging, yet remains a hard, non-convex inverse…
Instantons and Rarefaction Pulses as Pathways to Global Phase Coherence in Gain-Based Optical Networks
Richard Zhipeng Wang, Natalia G. Berloff
We investigate how to reliably remove unwanted global phase windings in gain-based optical oscillator networks, thereby ensuring convergence to the true synchronized configuration…
Fully Programmable Spatial Photonic Ising Machine by Focal Plane Division
Daniele Veraldi, Davide Pierangeli, Silvia Gentilini +10
Ising machines are an emerging class of hardware that promises ultrafast and energy-efficient solutions to NP-hard combinatorial optimization problems. Spatial photonic Ising machi…
