In this thesis optical diraction was used to study the static and dynamic properties of microscopic liquid-gas interfaces that span between adjacent ridges of a superhydrophobic surface. An observed interference phenomenon at grazing incident angle led to the development of optical gratings with a large spectral bandwidth, and an observed sensitive response of the liquid-gas interfaces to ultrasound led to the development of a superhydrophobic ber optical micro cavity that enables interferometric detection of the motion of a single microscopic meniscus.
