  • Publication number: 20200387016
    Abstract: Colloidal quantum wells have discrete energy states and electrons in the quantum wells undergo interband and intersubband state transitions. The transmissivity of a colloidal quantum well may be tuned by actively controlling the states of the colloidal quantum wells enabling ultrafast optical switching. A primary excitation source is configured to provide a primary excitation to promote a colloidal quantum well from a ground state to a first excitation state. A secondary excitation source is configured to provide a secondary excitation to the colloidal quantum well to promote the colloidal quantum well from the first excitation state to the second excitation state with the first and second excitation states being subbands in the conduction band of the colloidal quantum well.

  • Patent number: 10753545
    Abstract: An optically emissive material and, in particular, materials for use in single photon generation technologies, have multiple excited energy states that have different decay rates and can emit photons with different properties. A primary excitation radiation source is configured to apply primary radiation to an optically emissive material to excite the optically emissive material into a primary excited state. A secondary excitation radiation source is configured to apply secondary radiation to a thermal contribution material to generate thermal energy in the thermal contribution material. The thermal contribution material is physically configured to transfer thermal energy to the optically emissive material and excite the optically emissive material from the primary excited state to a secondary excited state for dynamic control of the emission rate, or emitted photon properties, of the optically emissive material.

  • Publication number: 20200249157
    Abstract: Systems and methods for performing refractometry include a primary waveguide, that has an injection end optically coupled to a laser and an output end optically coupled to a detector. A secondary waveguide has an interior, closed-loop optical path exhibiting total internal reflection, and an exterior surface having bound thereto a plurality of instances of a first binding entity type for an analyte. A portion of the exterior surface of the secondary waveguide is adjacent to the exterior surface of the primary waveguide, and a solution comprising a carrier fluid and an amplification complex includes a secondary particle bound to a second binding entity type for the analyte. The second binding entity type selected to bind to the analyte. The secondary particle is selected to have an index of refraction different from both the carrier fluid and the analyte.

  • Patent number: 10138134
    Abstract: A method for forming inorganic structures includes (a) transferring nanocrystals to a polar protic solvent using at least one chalcogenide precursor to produce a negatively-charged chalcogen-rich nanocrystal surface, (b) removing excess anions of the chalcogenide precursor, (c) introducing a metal salt to bind a divalent metal cation to the negatively-charged chalcogen-rich nanocrystal surface to regenerate a positively-charged metal-rich nanocrystal surface, and (d) removing excess divalent metal cations of the metal acetate salt.
