Fluidic photonic integrated circuit for in-line detection

We present a microfabricated fluidic photonic integrated circuit (FPIC) performing the detection function for flow cytometry. This device was entirely made of polymer using micromolding and capillary filling techniques. An array waveguide design was chosen to achieve superb sensitivity and the time-of-flight measurement for each particle flowing by. With multichannel sampling and cross-correlation analysis, the results show significant enhancement of detection sensitivity.
