Waveguide dimmable power splitter on the basis of microfluidics technology

Abstract

The present invention discloses a waveguide dimmable power splitter on the basis of a microfluidics technology, belongs to the field of integrated photonics, and relates to the optical waveguide device and technology. The waveguide dimmable power splitter provided by the invention is composed of a waveguide input port (1), two waveguide output ports (6, 10), a Y branch waveguide consisting of a waveguide 2, a waveguide 3, a waveguide 4, a waveguide 5, a waveguide 7 and a waveguide 9 and a microfluidic channel (8). After an optical signal is coupled with the waveguide input port (1) through fibers, the optical signal is propagated in an optical waveguide; and when the optical signal is arrived at the Y branch, the beam splitting of the optical signal happens, wherein the splitting ratio of the optical power is relative to the refractive index of mixed liquid in the microfluidic channel. Through changing of the refractive index of mixed liquid in the microfluidic channel, the output of the optical power of the output ports (6, 10) may be changed, and finally the dynamic control of the splitting ratio outputted by the power splitter may be realized. The waveguide dimmable power splitter on the basis of a microfluidics technology has advantages of wide modification scope, low dependence of wavelength and polarization, simple structure, easy design and operation, easy regulation and control and the like, and has extensive application prospects in an integration photon system and a microfluidic chip.
