  • Optical communication switch node
    Patent number: 6594050
    Abstract: A self-routing switching node that includes an optical associative memory processor that receives packet header information and a switching array coupled to the optical associative memory processor. The switching array receives control signals from the optical associative memory processor. The self-routing switching node also includes a buffer memory coupled to the optical associative memory processor that stores data packet information. The self-routing switching node further includes a vertical cavity surface emitting laser that transforms electronic packet header information into optical header information.
    Type: Grant
    Filed: January 3, 2001
    Date of Patent: July 15, 2003
    Assignee: Physical Optics Corporation
    Inventors: Tomasz P. Jannson, Guoda Xu, Freddie Lin
