Abstract:
1. An optical signal transmission device configured for transmitting light rays from a plurality of light emitters to a plurality of light receivers, the optical signal transmission device comprising: a substrate comprising a first side surface and a second side surface opposite to the first side surface; a plurality of first optical waveguide elements being substantially parallel with each other, and formed in the substrate; a plurality of second optical waveguide elements being substantially parallel with each other, and formed in the substrate, the second optical waveguide elements being substantially perpendicular to the first optical waveguide elements, the second optical waveguide elements intersected with the first optical waveguide elements, and thus forming a plurality of hollow junctions at cross portions of the first optical waveguide elements and the second optical waveguide elements to change the optical transmission path of light rays; a plurality of reflectors corresponding to the hollow junctions, each hollow junction housing one of the reflectors, the reflectors being capable of rotating around a rotating shaft thereof in the respective hollow junctions, each of the reflectors having a first reflecting surface and a second reflecting surface opposite to the first reflecting surface; and an integrated circuit configured for controlling rotating angles of the reflectors; wherein the first optical waveguide elements pass through the first side surface and the second side surface, the light emitters are positioned on the first side surface corresponding to the first optical waveguide elements, and the light receivers are positioned on the second side surface, and are corresponding to the first optical waveguide elements, each of the reflectors has four working states: the first working state is when the first reflecting surface is substantially perpendicular to the lengthwise direction of the first optical waveguide element, the second working state is when the first reflecting surface is substantially perpendicular to the lengthwise direction of the second optical waveguide element, the third working state is when the first reflecting surface faces the light emitters, and an included angle formed between the first reflecting surface and the lengthwise direction of the first optical waveguide element is about 45 degrees, and the fourth working state is when the first reflecting surface faces the light receivers, and an included angle formed between the first reflecting surface and the lengthwise direction of the first optical waveguide element is about 45 degrees.
