Abstract

This paper reports three dimensional (3D) liquid-liquid waveguide achieved simply using two flow streams in planar two dimensional (2D) microchannel by centrifugal force. When the two flow streams are transported in the curved microchannel, the inner flow stream is surrounded by the outer flow stream due to the centrifugal effect. As the refractive index of the inner flow streams is higher than the outer flow stream, a complete 3D waveguide is developed. The 3D liquid waveguide has low optical loss and simple control. It has wide range applications in biomedical, biological and chemical analyses in the near future.
