Vighen Pacradouni has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.
    Type: Application

  • Patent number: 6684008
    Abstract: The present planar photonic bandgap structures achieve improved control over radiation losses by employing layered dielectric structures. These structures control radiation losses incurred in connection with planar photonic bandgap structures and waveguides, waveguide bends, waveguide crossings, filters, switches and fiber-coupling structures in which such planar photonic bandgap structures are used.
