Computing with the complex nonlinear dynamics of an optomechanical oscillator

Babak Vosoughi Lahijani, Bingrui Lu, Cefe Lopez, Marcos Menendez, Miguel C. Soriano, Pedro David Garcia, Shulamit Edelstein, S{\o}ren Stobbe

The coherent phonon-lasing regime of an optomechanical oscillator supplies intrinsic nonlinearity and short-term memory for reservoir computing when its limit cycle is perturbed.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Using only a single chip-integrated device with 20 virtual nodes, we reconstruct nonlinear functions, predict the evolution of chaotic time series, and perform spoken digit classification on a two-digit sub-task.

C2weakest assumption

That perturbations applied to the phonon-lasing attractor reliably produce usable nonlinearity and short-term memory without external feedback loops or post-selection of operating points.

C3one line summary

The coherent self-sustained oscillation regime of an optomechanical oscillator functions as a physical reservoir computer for nonlinear transformations and memory-based tasks without external feedback.
