BARCODED END FACET PRINTED PHOTONIC CHIP AND BARCODE-GUIDED DIRECT LASER WRITING

NIST Inventors
Kartik Srinivasan and Edgar Perez
patent description (1) Disclosed is a barcoded end facet printed photonic chip comprising: an optically transparent direct laser writing substrate comprising a transverse waveguide writing surface to receive a direct write laser light for off-axis direct write laser printing and a facet surface to

QUANTUM-ENABLED FLOW CYTOMETER

NIST Inventors
Sergey Polyakov and Ivan Burenkov
patent description We invented a flow cytometer that can self-calibrate in an absolute way that can reach the sensitivity for quantification and enumeration of a single and small number of biological markers per a biological entity. The cytometer uses a photon-number resolving detector (or a

SYNCHRONIZER AND SYNCHRONIZING TRANSFER OVER AN OPTICAL LINK

NIST Inventors
Laura Sinclair , Nathan R Newbury , William C. Swann and JD Deschenes
patent description (1) Disclosed is a synchronizer for synchronizing transfer over an optical link, the synchronizer comprising: a frequency reference oscillator that produces a frequency reference signal; a tracking optical timing source in communication with the frequency reference oscillator and

OPTICAL REFRACTION BAROMETER

NIST Inventors
Kevin O Douglass , Stephen Eckel , Jacob Edmond Ricker and Jay H. Hendricks
patent description In short a method to improve upon the current FLOC system, for measuring pressure based on refractivity changes, by using a single laser and direct measure of the difference between the lasers without heterodyne measurement.

QUANTUM WAVEGUIDE INFRARED PHOTODETECTOR

NIST Inventors
Eric Stanton
patent description The QWIP was first demonstrated in 1987 [1] and consistent research since then has improved the QWIP detection efficiency, but only for surface normal detection. Development of the QWIP was originally intended for infrared focal plane arrays suitable for infrared cameras. One

SINGLE QUANTUM EMITTER SINGLE PHOTON SOURCE AND PRODUCING A SINGLE PHOTON STREAM

NIST Inventors
Marcelo Davanco
patent description The invention is an integrated photonic device which allows production of a pure stream of on-chip waveguide-bound indistinguishable single-photons from the resonance fluorescence of a single quantum emitter embedded in a multimode on-chip waveguide, for which the quantum emitter

CHARGE DETECTOR AND PROCESS FOR SENSING A CHARGED ANALYTE

NIST Inventors
Arvind Balijepalli and Curt A. Richter
patent description (1) Disclosed is a charge detector to operate a dual-gated field effect transistor at a quantum capacitance limit for performing ultrasensitive biosensing, the charge detector comprising: a charge sensor that senses a charged analyte and produces a charge signal in response to
