    Abstract: Methods and apparatus are provided for detecting one or more contaminant particles in an environment with an optical sensor. The sensor includes at least one optical waveguide in a resonant arrangement and a light source positioned in an environment in which the presence of a contaminant particle is sought to be determined. The at least one optical waveguide is of a diameter that an evanescent tail of the lightwave extending there through extends into the environment and is reactive to at least one contaminant particle in the surrounding environment. A detector is positioned to receive light indicative of the sharpness of the optical resonance lineshape of the optical resonator at a pre-selected optical wavelength. The detected information determines the specific contaminant particle in the environment and the concentration of the contaminant particle in the environment.

    Abstract: An integrated optical device for measuring the refractive index of a fluid comprises a light guide formed on a substrate and having a guiding layer for carrying light beams, inserted between a lower layer and an upper layer having refractive indices below that of the guiding layer. The device includes an interaction measurement zone of the light guide for coming into contact with the fluid, the upper layer at the measurement zone having a thickness less than the penetration distance of the evanescent wave of the guided light beam. Outside the interaction zone, that upper layer has a thinckness greater than the penetration distance of the same evanescent beam. The device also has an interferometric optical system at least partly formed in the light guide and having a reference optical circuit and a measurement optical circuit including the measurement zone, for measuring the phase shift introduced by an effective index change of the guided mode due to the fluid.
