  • Patent number: 11646790
    Abstract: An optical system (100) is described including: a reconfigurable optical device (103) with multiplexing wavelength division, comprising a plurality of actuators (A1-AN) and having associated a number of optical channels (M) and a number of degrees of freedom (N) lower than the number of optical channels; an optical stimulus source (106) connected to said reconfigurable optical device (103) to provide an optical stimulation signal (Sin) having a wavelength band including a plurality of wavelengths associated with the optical channels; an optical-electric conversion device (200) configured to receive from said reconfigurable optical device (103) an optical monitoring signal (Sout) corresponding to the optical stimulation signal (Sin) and to provide a group of electrical signals of intensity (SEL1-SELK) each representative of an intensity of the optical monitoring signal (Sout) evaluated at a relative wavelength included in said band.

  • Patent number: 11313793
    Abstract: An opto-magnetic device includes an integrated optical circuit having an input for an input optical radiation and at least one output for an output optical radiation. The optical circuit defines an area sensible to the variations of a local refraction index probed by the optical radiation, destined to come in contact with the sample. A plurality of probe molecules are included to anchor to the sensible area, and a plurality of magnetic particles are included to anchor to molecules of the analyte, bound to the probe molecules upon a molecular recognition. A magnetic actuator is configured to generate a variable magnetic field and oscillate the magnetic particles to cause variation of the refraction index probed by the optical radiation in the sensible area, and a variation of at least one characteristic parameter of the output optical radiation correlated to a concentration of the molecules of the analyte.
