Dual-frequency-comb spectrometer and spectroscopy method for spectroscopic investigation of a sample
Patent number: 10969276Abstract: A dual-frequency-comb spectrometer and a method for spectroscopic investigation of a sample are described. The spectrometer includes first and second frequency comb devices for emitting laser pulses along first and second light paths, wherein the repetition frequency of the laser pulses emitted by the second device is offset from that of the first device. First and second multi-core waveguides including at least two separate single core waveguides having field-coupling via a coupling gap therebetween are arranged in the first and second light paths. The sample is irradiated by the second frequency comb in the second light path. A detector device is arranged in a third light path where the first and second light paths are combined, for simultaneously sensing the first frequency comb and the second frequency comb after an interaction with the sample. A computing device receives output of the detector device and calculates spectroscopic properties of the sample.Type: GrantFiled: June 19, 2019Date of Patent: April 6, 2021Assignee: ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNE (EPFL)Inventors: Tobias Kippenberg, Hairun Guo, Junqiu Liu, Wenle Weng -

Patent number: 10952627Abstract: A preferred frequency is identified, being usable to stimulate a neurological target within a mammalian body using at least one microelectrode positioned at or near the target. To establish efficient and effective stimulation, an impedance analyzer is provided for measuring electrical impedance values indicative of a microelectrode-tissue interface across a range of different frequencies. A preferred one of the measured electrical impedance values is identified as being closest to a pure resistance. The neurological target can then be stimulated at or near the frequency associated with the preferred impedance value (peak resistance frequency), thereby promoting desirable traits, such as optimum charge transfer, minimum signal distortion, increased stimulation efficiency, and prevention of microelectrode corrosion. The peak resistance frequency can be used to determine an preferred pulse shape.Type: GrantFiled: December 31, 2018Date of Patent: March 23, 2021Assignee: ECOLE POLYTECHNIQUE FEDERALE DE LAUSANNEInventors: André Mercanzini, Philippe Renaud
