  • Publication number: 20180306704
    Abstract: The invention relates to a device comprising: a resonant tank (100) consisting of two primary tubes (105, 106) which are closed on the ends thereof and interconnected, close to each of the ends thereof, by two secondary tubes (109, 110), and provided with a gas-introducing means (118, 119); a first laser source (112) modulated to a first resonance frequency of the tank, which supplies an excitation energy in at least one of the primary tubes, with an emission wavelength corresponding to a local maximum absorption wavelength for a first gas, for generating a first stationary wave propagating along the secondary tubes; a second laser source (117) modulated to a second resonance frequency of the tank, which supplies an excitation energy in at least one of the secondary tubes, with an emission wavelength corresponding to a local maximum absorption wavelength for a second gas, for generating a second stationary wave propagating along the primary tubes; at least one acoustoelectric transducer (103, 104, 123, 124) a

  • Publication number: 20120266655
    Abstract: A photoacoustic detection device including a nanophotonic circuit including a first chip on which is formed at least one optical waveguide and in which is formed a set of cavities defining a Helmholtz resonator; at least one optical source capable of emitting an optical signal in a given wavelength range, capable of being modulated at an acoustic modulation frequency, this source being attached to the first chip; a second chip forming a cap for said cavities and including acoustic sensors; and electronic circuits for processing the output of the acoustic sensors formed in the first or the second chip.
