Patent number: 10481089Abstract: A detection system includes a planar plasmonic element for analyzing an analyte, the plasmonic element having dielectric and metallic regions, the plasmonic element emitting light that carries detected information; and a planar two-dimensional image sensor positioned in non-parallel angled relationship with respect to a plane of the plasmonic element to enhance a spatial image resolution for the light that carries detected information with respect to at least a portion of the light.Type: GrantFiled: December 3, 2013Date of Patent: November 19, 2019Assignee: INTEGRATED PLASMONICS CORPORATIONInventor: Robert Joseph Walters

Patent number: 10241347Abstract: A spatial filter is made by forming a structure comprising a focusing element and an opaque surface, the opaque surface being disposed remotely from the focusing element in substantially the same plane as a focal plane of the focusing element; and by forming a pinhole in the opaque surface at or adjacent to a focal point of the focusing element by transmitting a substantially collimated laser beam through the focusing element so that a point optimally corresponding to the focal point is identified on the opaque surface and imperfection of the focusing element, if any, is reflected on the shape and position of the pinhole so formed.Type: GrantFiled: September 1, 2017Date of Patent: March 26, 2019Assignee: INTEGRATED PLASMONICS CORPORATIONInventors: Michael Yagoda Shagam, Robert Joseph Walters

Patent number: 9995623Abstract: A spectroscopic device, which may be a handheld spectroscopic light source, which uses ambient light as a primary broadband light source, but which may be supplemented with an auxiliary light source to supplement band regions which may be deficient in the broad band source. The spectroscopic device makes use of a number of parallel control channels to monitor for sufficient light and to compensate for variations in the input light levels.Type: GrantFiled: December 3, 2013Date of Patent: June 12, 2018Assignee: INTEGRATED PLASMONICS CORPORATIONInventor: Robert Joseph Walters

Patent number: 9404797Abstract: A spectroscopic measurement system, which may utilize multiple plasmonic filters associated with a cuvette to monitor different wavelengths of light. The spectroscopic measurement system may measure absorbance and or fluorescence, and may have built-in low cost CMOS image sensor(s). Reagents and samples may be introduced to the cuvette from a fluidics manifold. Multiple sets of combined cuvettes, image sensors and plasmonic filters may utilize a single fluidics manifold for reagent and sample distribution.Type: GrantFiled: December 3, 2013Date of Patent: August 2, 2016Assignee: INTEGRATED PLASMONICS CORPORATIONInventor: Robert Joseph Walters

Publication number: 20140045730Abstract: An integrated plasmonic sensing device is monolithically integrated and provides marker-free detection (eliminating the need to use fluorescent or absorbing markers) and in-situ monitoring of conditions at each detection region. The integrated plasmonic sensing device includes a plasmonic backplane disposed on a monolithically integrated image sensor. One or more plasmonic scattering regions and one or more plasmonic via regions laterally offset from the plasmonic scattering regions are provided in the plasmonic sensing device. Guided plasmonic modes mediate power transfer through the plasmonic backplane to one or more underlying image sensor pixels.Type: ApplicationFiled: October 10, 2013Publication date: February 13, 2014Applicant: INTEGRATED PLASMONICS CORPORATIONInventor: Robert Joseph WALTERS
