Filed:
Mar 3, 2021
Appl. No.:
17/191275
Inventors:
- Armonk NY, US
Chi Xiong - Yorktown Heights NY, US
Swetha Kamlapurkar - Yorktown Heights NY, US
Hanhee Paik - Danbury CT, US
Jason S. Orcutt - Katonah NY, US
International Classification:
H01P 7/00
G02B 6/13
H01P 11/00
Abstract:
Techniques regarding quantum transducers are provided. For example, one or more embodiments described herein can include an apparatus that can include a superconducting microwave resonator having a microstrip architecture that includes a dielectric layer positioned between a superconducting waveguide and a ground plane. The apparatus can also include an optical resonator positioned within the dielectric layer.

Efficient Photonic Circuits For Liquid-Cooled High-Density Datacenters

US Patent:
2021002, Jan 28, 2021
Filed:
Jul 22, 2019
Appl. No.:
16/518131
Inventors:
- Armonk NY, US
Douglas M. Gill - South Orange NJ, US
William M. Green - Irvington NY, US
Jason S. Orcutt - Katonah NY, US
Jessie C. Rosenberg - Mount Vernon NY, US
Eugen Schenfeld - South Brunswick NJ, US
Chi Xiong - Yorktown Heights NY, US
International Classification:
G02B 6/12
G02B 6/30
H05K 7/20
Abstract:
Photonic circuits are disclosed having an efficient optical power distribution network. Laser chips (InP) having different wavelengths are flip-chip assembled near the center of a silicon photonic chip. Each InP die has multiple optical lanes, but a given die has only one wavelength. Waveguides formed in the photonic chip are optically connected to the lanes, and fan out to form multiple waveguide sets, where each waveguide set has one of the waveguides from each of the different wavelengths, i.e., one waveguide from each InP die. The waveguide network is optimized to minimize the number of crossings that any given waveguide may have, and no waveguide having a particular wavelength crosses another waveguide of the same wavelength. The unique arrangements of light sources and waveguides allows the use of a smaller number of more intense laser sources, particularly in applications such as performance-optimized datacenters where liquid cooling systems may be leveraged.

Feed-Forward Spectral Calibration Methodology For Line-Scanned Tunable Laser Absorption Spectroscopy

US Patent:
2020030, Oct 1, 2020
Filed:
Mar 26, 2019
Appl. No.:
16/364544
Inventors:
- ARMONK NY, US
- PRINCETON NJ, US
Chi Xiong - Yorktown Heights NY, US
Eric Zhang - Yorktown Heights NY, US
Gerard Wysocki - Princeton NJ, US
International Classification:
G01N 21/39
G01N 21/25
Abstract:
A generalized feed-forward method for accurate tunable laser absorption spectroscopy includes generating a laser beam. The generated laser beam is directed down a reference path and a test/sample path. One or more parameters are extracted from the reference path. The one or more parameters, extracted from the reference path, are used as feed-forward, to adjust spectral analysis of the test/sample path to detect a composition and/or concentration of an analyte gas within the test/sample path. The extraction of the one or more parameters from the reference path and the spectral analysis of the test/sample path are performed substantially concurrently.

Tunable Diode Laser Absorption Spectroscopy With Corrected Laser Ramping Nonlinearities

US Patent:
2019018, Jun 20, 2019
Filed:
Dec 19, 2017
Appl. No.:
15/846912
Inventors:
- Armonk NY, US
Chu Cheyenne TENG - Yorktown Heights NY, US
Gerard WYSOCKI - Yorktown Heights NY, US
Chi XIONG - Yorktown Heights NY, US
Eric ZHANG - Yorktown Heights NY, US
International Classification:
G01N 21/45
G01J 3/45
Abstract:
A tunable diode laser absorption spectroscopy device includes a tunable diode laser. A laser driver is configured to drive the diode laser and ramp it within a particular frequency range. An analyte gas container, a reference gas container, and a fringe generating device are configured to receive the laser therethrough. An optical detector is configured to detect the laser after it has passed through the analyte gas container and/or the reference gas container, and the in-line fringe generating device. An acquisition card is configured to sample an output of the optical detector. A spectral analyzer is configured to receive output data from the acquisition card, determine a spectrum of the output data, decouple the fringe spectrum from the measured spectrum, calibrate the spectrum based on an expected ideal spectrum of both the fringe and reference gas, and determine a composition of the analyte based on the calibrated spectrum.
