The invention relates to a two dimension electro-
optical switch array device based on a microfluidic technology, adopting a structure of an air storage layer plus a
waveguide layer plus a fluid storage layer, wherein, the
waveguide layer comprises a flat
basement (7), a
waveguide structure (8) which is arranged in a
matrix form is arranged on the
basement, a fluid cavity (9) is arranged at a waveguide cross node, the edge of the
basement is provided with an air-fluid connecting channel (10),and an electronic control
optical switch unit array (11) is arranged at the fluid cavity (9) at the waveguide cross node; the air storage layer is a sealing container (1) which stores the air, the edge of the container is provided with an air pressure adjusting control hole (4), an air-fluid connecting
open hole (5) at the bottom part penetrates the waveguide layer and is communicated with the fluid storage layer, an
electrode open hole (6) which is consistent with the waveguide cross node is arranged on the container, thereby being convenient to show an
optical switch control unit electrode (18); the fluid storage layer is a container which is open ended at the upper end and stores the fluid, the fluid storage layer is sealed through combining the waveguide layer, the microcontainer inner
surface tension is changed through an electro
wetting effect to adjust the height of a
liquid column, thereby realizing total reflection and
total transmission of a
light beam and further realizing the opening and closing actions of the light.
