  • Grating coupled converter
    Patent number: 8391656
    Abstract: A chip includes a grating coupler and an optoelectronic converter. The grating coupler is patterned to extract a first fraction of incident light and to transmit a second fraction of the incident light as an output optical signal from the chip. The optoelectronic converter receives the first fraction of the incident light from the grating coupler and produces an electrical signal from light received.
    Type: Grant
    Filed: July 29, 2010
    Date of Patent: March 5, 2013
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Sagi V. Mathal, David A. Fattal

  • Device with tunable plasmon resonance
    Patent number: 8081850
    Abstract: A device includes a resonator capable of supporting a plasmon mode, a gain structure arranged to couple energy into the resonator, and a memristive layer arranged to provide an interaction with the plasmon mode. An electric signal applied to the memristive layer can change the interaction and change a resonant frequency of the plasmon mode.
