  • Integrated plasmonic modulator
    Publication number: 20220236619
    Abstract: An optoelectronic device (20) includes thin film structures (56) disposed on a semiconductor substrate (54) and patterned to define components of an integrated drive circuit, which is configured to generate a drive signal. A back end of line (BEOL) stack (42) of alternating metal layers (44, 46) and dielectric layers (50) is disposed over the thin film structures. The metal layers include a modulator layer (48), which contains a plasmonic waveguide (36, 99, 105) and a plurality of electrodes (30, 32, 34, 96, 98, 106), which apply a modulation to surface plasmons polaritons (SPPs) propagating in the plasmonic waveguide in response to the drive signal. A plurality of interconnect layers are patterned to connect the thin film structures to the electrodes.

  • Integrated plasmo-photonic biosensor and method of use
    Patent number: 11204326
    Abstract: The invention relates to a device comprising a first optical Mach-Zehnder interferometric sensor (MZI1) with a large FSR, wherein a plasmonic waveguide (107) thin-film or hybrid slot, is incorporated as transducer element planar integrated on Si3N4 photonic waveguides and a second optical interferometric Mach-Zehnder (MZI2), both comprising thermo-optic phase shifters (104, 106) for optimally biasing said MZI sensor (MZI1) and MZI as variable optical attenuator VOA.
