Abstract
An optical waveguide comprises multiple layers of solid-state material disposed on a substrate. One of the layers is a lifting-gate valve made of a high refractive index material. The device provides for better optical confinement in microfluidic channels, and has the capability to integrate both optical signals and fluid sample processing. The optical paths on the chip are reconfigurable because of the use of a movable microvalve that guides light in one of its positions.
