Researchers demonstrated an electrically driven surface acoustic wave phonon laser on a chip, generating gigahertz SAWs that could enable all radio processing on a single, smaller, more power-efficient smartphone chip.
Researchers have demonstrated a solid-state surface acoustic wave phonon laser on a tiny chip, creating coherent GHz vibrations by stacking lithium niobate and indium gallium arsenide. This chip-level device amplifies surface waves without needing an external RF source, potentially enabling all-in-one-chip signal processing for wireless communications and reducing power and size in future smartphones.
