Abstract

Liquid optical waveguides take the advantages of tunable, reconfigurable and adaptive to solid-state waveguides, making them as highly dynamic optofluidic devices. However, the effect of diffusive dispersion between the core flow stream and cladding flow stream makes the liquid waveguide more complex than the traditional step-index or graded-index waveguides. Here we introduce a liquid waveguide integrated in a finite rectangular microchannel. The ability of the flowing streams of miscible fluids to create gradients in optical properties by diffusion causes some distinguish new phenomena, such as quasi-periodic ray path, beaming, Talbot effect, and dispersion, are investigated both analytically and experimentally.
