Abstract

This paper reports a phenomenon of light in which light is split by three flow streams with a large tunable angle up to 30°. The core flow stream with lower refractive index is sandwiched by the cladding flow streams with higher refractive index. The miscible fluids creates a refractive index gradient in the microchannel that split an incident beam into two propagating paths. The angle is controlled by the composition of the fluids and the flow rates. The optofluidic splitter has high potential applications in biomedical and chemical solution measurement and detection.
