  • Patent number: 11960809
    Abstract: Provided is an improved method, system, and computer program product to implement simulation for photonic devices. A composite, multi-domain simulation model is disclosed, with connected domain-specific representations that allow the use of the most relevant simulator technology for a given domain. The model has external connection points either expressed as actual ports or virtual ones, embodied by simulator API calls in the model.
    Type: Grant
    Filed: January 10, 2022
    Date of Patent: April 16, 2024
    Assignees: ANSYS, INC., CADENCE DESIGN SYSTEMS, INC.

  • Publication number: 20230333367
    Abstract: A system and method are provided for simulating circuits that transmit bidirectional signals between some ports using simulators designed originally for electrical circuits and systems, that eliminate the need for different port interfaces. The system and method can be applied to simulate photonic circuits either standalone or integrated with electrical circuits and systems. In one method implemented by the system potential and flow representations, available for example in Verilog-A simulators, are used to create bidirectional signals on a single bus line to transmit optical signals. In another method implemented by the system, the system auto-configures each optical port type as left or right at runtime or during a pre-simulation initialization to allow for bidirectional signals with a single port interface.

  • Patent number: 11537771
    Abstract: A system and method are provided to enable non-quantum experts to schematically represent, simulate and quantify the performance of physically realistic photonic quantum circuits. The framework offers the flexibility for users—not necessarily familiar with the fundamentals of quantum mechanics—to create circuits and work with simple inputs and outputs, while the complexities of manipulating high dimensionality quantum Hilbert spaces supporting photonic and physical quantum object states are handled with the use of purpose-built tools. The tools include a user-friendly method for defining classical photonic circuits which may be coupled to physical objects such as qubits, quantum input states, as well as classical and quantum measurement devices. The tools feature classical-to-quantum S-matrix conversion, quantum S-matrix extraction, as well as capabilities for defining and extracting quantum error parameters.

  • Patent number: 10095816
    Abstract: A method and apparatus for simulating a mesh element of an anisotropic medium are provided. A unitary transformation is applied to an initial coordinate system of the mesh element by a transformation module to produce a transformed reference coordinate system of the mesh element. Maxwell's equations for the mesh element are solved by an update generation module using computational methods to obtain an electric field tensor and an electric displacement field tensor within the mesh element. A unitary transformation to the electric field tensor and the electric displacement tensor are performed by a transformation module to calculate a corresponding electric field tensor and electric displacement tensor for the mesh element in the initial coordinate system.
