Abstract
An optical sensing device includes a support with an aperture. The optical sensing device can removably hold a sample against the support around the aperture. Accordingly, a portion of the sample is free to deform through the aperture in response to a change in an environmental condition. An optical waveguide is fixedly arranged with respect to the support whereby an end of the optical waveguide faces the aperture. The end of the optical waveguide forms an optical interferometric cavity with a refractive index discontinuity at a surface of the portion of the sample that is free to deform through the aperture.
