Abstract

There has been recent growing interest in liquid optical components for a range of applications, including lenses, optical sensing, and microfluidic lasers and optical switches [1]. The shape of such components can be manipulated electrically or hydrostatically to simply tune the optical properties. One notable example is the recent advance in microfluidic optical waveguides, in which a high index core liquid flows through a second, lower index cladding fluid [2].
