Demonstration of chip-based coupled degenerate optical parametric oscillators for realizing a nanophotonic spin-glass

The use of a photonic network of coupled degenerate optical parametric oscillators for solving complex optimisation problems would require scalable integration capabilities. Here, the authors exploit χ (3) nonlinearity in SiN to demonstrate on-chip phase-tunable coupling between two DOPO based Ising...

Sumario:The use of a photonic network of coupled degenerate optical parametric oscillators for solving complex optimisation problems would require scalable integration capabilities. Here, the authors exploit χ (3) nonlinearity in SiN to demonstrate on-chip phase-tunable coupling between two DOPO based Ising nodes.
