  • Slanted Bragg Grating Refractometer, Using the Optical Power Diffracted to the Radiation-Mode Continuum
    Publication number: 20080129985
    Abstract: This refractometer includes at least one optical waveguide (2) comprising at least one slanted Bragg grating (4), formed in a part of the waveguide, which is placed in contact with the medium (7) of which the refraction index is to be determined, a light source (10) coupled to the waveguide in order to send this light there and have it interact with the grating, means (17) for measuring the optical power of the light diffracted to the radiation-mode continuum, when the light transmitted by the source interacts with the grating, and electronic processing means (22) for supplying the value of the refraction index of the medium based on this optical power.
