Researchers have demonstrated a vertical organic field-effect transistor that monolithically integrates a volatile, nonlinear optical reservoir with a linear, nonvolatile electrical readout within a single device footprint.
This structural separation ensures that the reservoir dynamics and memory retention can be optimized independently within the same physical structure.
This spectral diversity allows a single device to project multi-wavelength optical sequences into orthogonal reservoir subspaces, effectively enabling multi-wavelength grouped reservoir computing.
The output of each virtual node was derived directly from experimentally measured optical conductance responses to ensure physical fidelity.
