Latest Patents

One of Chaohan Cui's latest patents is titled "Estimation of a parameter of a cavity on an integrated photonic chip." This patent presents a low-cost, data-fitting-free robust methodology designed to distinguish the coupling condition of an arbitrary resonance. It is applicable, for instance, to a micro-resonator within a multi-micro-resonator optical integrated circuit. The method involves registering the resonator cavity response to a rapid-phase shift of the on-resonance pump field. By analyzing the time-dependent transmission characteristics acquired with an optical detector, the method allows for a more accurate estimation of the intrinsic loss compared to related art. This innovation facilitates practical inspection of massively integrated photonic platforms with micro-resonators.

Another notable patent is "Quantum receiver and method for decoding an optical signal." This invention features a quantum receiver that decodes optical signals using a beamsplitter to interfere the optical signal with a local-oscillator field. It generates a displaced field, which is then detected by a single-photon detector. The signal-processing circuit determines the measurement outcome based on the electrical output of the detector and employs a feed-forward machine-learning model to optimize the next displacement. This adaptive measurement approach reduces the error probability of the decoded symbol and enhances the efficiency of the signal-processing circuit.
