Researchers at the University of Rochester developed an electro-optical modulator using a thin film of lithium niobate (LN) bonded on a silicon dioxide layer. The resulting electro-optical modulator is described as the smallest such device ever created, potentially paving the way for large-scale LN photonic integrated circuits.The modulator project builds upon the lab’s previous use of lithium niobate to create a photonic nanocavity—another key component...
