N2 - In this letter, an optical method based on the liquid core/liquid cladding (L2) waveguides for flow rate measurement is presented. The flow rate of the fluid passing through one of the claddings of the L2 waveguide is measured through monitoring the changes in the output power of the waveguide. The performed finite-element analysis shows that adjusting the flow rate of one cladding with respect to the other one modulates the output power of the waveguide, systematically. Hence, it can be used as a new practical method of measuring the flow rates in a Lab-on-a-Chip device. We have carried out several sets of experiments and achieved the maximum resolution of 30 nL/min with a tunable detection range in measuring the flow rate.
