Abstract

In this paper, a microfuidic Mach-Zehnder (M-Z) filter is proposed. It has the advantages of small size, simple structure, convenient manufacture and flexible adjustment. In the proposed filter, one arm of the M-Z Interferometer is the sensing arm and the other arm is the reference arm. The sensing arm has adjustable refractive index because the microchannel is filled with liquid which could be replaced. The reference arm is not contacted with the outside. The comb filter spectrum of the M-Z filter can be adjusted by changing the refractive index of liquid in the microchannel. This paper presents the structure, working principle and related theories of the microfluidic M-Z filter. The proposed M-Z filter can promote the application of microfluidics in the optical communication.
