Patent number: 10718668Abstract: State-of-the-art portable Raman spectrometers use discrete free-space optical components that must be aligned well and that don't tolerate vibrations well. Conversely, the inventive spectrometers are made with monolithic photonic integration to fabricate some or all optical components on one or more planar substrates. Photonic integration enables dense integration of components, eliminates manual alignment and individual component assembly, and yields superior mechanical stability and resistance to shock or vibration. These features make inventive spectrometers especially suitable for use in high-performance portable or wearable sensors. They also yield significant performance advantages, including a large (e.g., 10,000-fold) increase in Raman scattering efficiency resulting from on-chip interaction of the tightly localized optical mode and the analyte and a large enhancement in spectral resolution and sensitivity resulting from the integration of an on-chip Fourier-transform spectrometer.Type: GrantFiled: August 8, 2018Date of Patent: July 21, 2020Assignee: Massachusetts Institute of TechnologyInventors: Tian Gu, Derek Matthew Kita, Juejun Hu

Patent number: 10386237Abstract: A spectrometer includes an interferometer having a first interference arm and a second interference arm to produce interference patterns from incident light. At least one of the interference arms includes a series of cascaded optical switches connected by two (or more) waveguides of different lengths. Each optical switch directs the incident light into one waveguide or another, thereby changing the optical path length difference between the first interference arm and the second interference arm. This approach can be extended to multi-mode incident light by placing parallel interferometers together, each of which performs spectroscopy of one single mode in the multi-mode incident light. To maintain the compactness of the spectrometer, adjacent interferometers can share one interference arm.Type: GrantFiled: May 22, 2018Date of Patent: August 20, 2019Assignee: Massachusetts Institute of TechnologyInventors: Juejun Hu, Tian Gu, Hongtao Lin, Derek Matthew Kita, Anuradha M.

Patent number: 10359239Abstract: A heat exchanger is disclosed. The heat exchanger includes a heat exchange member that includes a first extruded member having a first end and a second end. The first extruded member forms a plurality of fluid passages that are in fluid communication with the first end of the first extruded member and the second end of the first extruded member. At least one of the fluid passages is an inlet fluid passage and at least one of the fluid passages is an outlet fluid passage. A plug is fixedly coupled to the second end of the first extruded member. The plug forms a plug fluid passage that fluidically interconnects the inlet fluid passage at the second end of the first extruded member with the outlet fluid passage at the second end of the first extruded member.Type: GrantFiled: January 11, 2016Date of Patent: July 23, 2019Assignee: Lockheed Martin CorporationInventors: Eugene Charles Jansen, Derek Matthew Beckner, Scott Morris Maurer, Kevin Patrick Miller, Nicholas J.

Patent number: 10240980Abstract: An apparatus for generating a spectral image includes a filter to receive incident light. The filter has a variable refractive index. The apparatus also includes a modulator, operably coupled to the filter, to modulate the variable refractive index of the filter so as to generate a plurality of optical patterns from the incident light. The plurality of optical patterns represents the spectral image and each optical pattern in the plurality of optical patterns corresponds to a different modulation of the variable refractive index. The apparatus further includes a detector, in optical communication with the filter, to detect the plurality of optical patterns.Type: GrantFiled: May 23, 2017Date of Patent: March 26, 2019Assignee: Massachusetts Institute of TechnologyInventors: Juejun Hu, Tian Gu, Kazumi Wada, Anuradha Murthy Agarwal, Lionel Cooper Kimerling, Derek Matthew Kita, Junying Li, Fleur Jacolien Fok
