Latest Patents

Lauwers' latest patents include an "Optical device for detecting an acoustic wave" and a "Photoacoustic or photothermal detector comprising an optical transducer." The first invention relates to a device and method for detecting an acoustic wave propagating toward a membrane, which carries a waveguide with an optical cavity defining a resonant frequency. The device utilizes a light source to direct a light wave into the optical cavity, with a servo circuit that controls the wavelength of the light wave to match the resonant wavelength of the optical cavity. This allows for monitoring the variation in the wavelength of the light wave, enabling the estimation of the amplitude of the acoustic wave.

The second patent describes a device and method for detecting an analyte in a medium. An exciting light source produces a light wave that heats the medium, and the device includes a transducer for detecting the heating. Depending on the embodiment, the transducer can be either a thermal transducer or an acoustic transducer, both utilizing a membrane with a waveguide that contains a resonant optical cavity. The transduction process is achieved by analyzing variations in the resonant wavelength of the optical cavity.
