  • Negative refractive index device for generating terahertz or microwave radiation and method of operation thereof
    Patent number: 7745790
    Abstract: A negative refractive index device and a method of generating radiation. In one embodiment, the device includes: (1) an optical input configured to receive light and (2) an optical medium having a negative index of refraction and a second-order nonlinearity proximate a center frequency of the light, coupled to the optical input and configured to resonate in response to the light to yield radiation having a phase velocity based on a group velocity of the light.
    Type: Grant
    Filed: November 20, 2007
    Date of Patent: June 29, 2010
    Assignee: Alcatel-Lucent USA Inc.
    Inventors: Aref Chowdhury, John A. Tataronis
  • Nonlinear optical devices based on metamaterials
    Patent number: 7586670
    Abstract: An apparatus includes one or more optical couplers, an optical medium, and an optical pump source. The optical medium behaves as a negative refractive index material over a frequency range. The one or more optical couplers are configured to provide first and second optical inputs to the optical medium and to provide an optical output from the optical medium. The optical pump source is coupled by one of the one or more optical couplers to deliver pump light to the optical medium.
