Abstract

We present an optofluidic device for switching light from multiple inputs to one common output. The device uses a microfluidic channel filled with high index of refraction oil as a waveguide, and moves low refractive index interruptions in the form of aqueous droplets through the channel. Whenever a droplet passes one of the optical inputs, this specific input is switched through to the output. This produces a running switching of one output following the other creating a 8x1 multiplexer.
