Patent number: 12216158Abstract: Systems and methods for testing a photonic IC (PIC) with an optical probe having an out-of-plane edge coupler to convey test signals between the out-of-plane probe and an edge coupled photonic waveguide within a plane of the PIC. To accommodate dimensions of the optical probe, a test trench may be fabricated in the PIC near an edge coupler of the waveguide. The optical probe may be displaced along one or more axes relative to a prober to position a free end of the prober within the test trench and to align the probe's out-of-plane edge coupler with an edge coupler of a PIC waveguide. Accordingly, a PIC may be probed at the wafer-level, without first dicing a wafer into PIC chips or bars. The optical probe may be physically coupled to a prober through a contact sensor to detect and/or avoid physical contact between probe and PIC.Type: GrantFiled: November 24, 2020Date of Patent: February 4, 2025Assignee: Intel CorporationInventors: Jeremy Hicks, Hari Mahalingam, Christopher Seibert, Eric Snow, Harel Frish

Patent number: 11482560Abstract: A monolithically integrated, tunable infrared pixel comprises a combined broadband detector and graphene-enabled tunable metasurface filter that operate as a single solid-state device with no moving parts. Functionally, tunability results from the plasmonic properties of graphene that are acutely dependent upon the carrier concentration within the infrared. Voltage induced changes in graphene's carrier concentration can be leveraged to change the metasurface filter's transmission thereby altering the “colors” of light reaching the broadband detector and hence its spectral responsivity. The invention enables spectrally agile infrared detection with independent pixel-to-pixel spectral tunability.Type: GrantFiled: July 16, 2020Date of Patent: October 25, 2022Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Thomas Edwin Beechem, III, Michael Goldflam, Anna Tauke-Pedretti, Isaac Ruiz, David W.
