Abstract

The present invention discloses an integrated 16-way optical divider and a preparation method thereof. The optical divider allows signal light to generate multimode interference coupling in a coupling waveguide to rapidly and uniformly disperse the signal light along the cross section direction of the transmission direction so as to increase the area of the signal light output interface and realize the one-way to multi-way signal light division in the size of a light split area with short length. The optical divider comprises a substrate layer, and lower cladding is prepared at the upper surface of the substrate layer; a package layer is arranged at the upper surface of the lower cladding; a rectangle groove is arranged on the package layer; a rectangle interference waveguide is arranged in the rectangle groove; 11 layers of rectangle interference waveguide are arranged, and upper cladding is arranged at the last rectangle interference waveguide to form the coupling waveguide through adoption of the 11 layers of rectangle interference waveguide and allow the signal light to perform interference coupling in the coupling waveguide so as to realize multi-way light split. The integrated 16-way optical divider and the preparation method thereof are mainly used in the optical communication light split technology.

Description

technical field [0001] The invention relates to the field of optical communication light splitting technology, in particular to an integrated one-point 16-way optical splitter and a preparation method thereof. Background technique [0002] At present, there are two ways to manufacture optical splitters. One is the fused tapered optical splitter, but due to the large size of the fused drawn tapered optical splitter, it will take up a lot of space; the other is The planar waveguide optical splitter is the mainstream direction of the current technology development, but the splitting distance of the tapered section of the planar waveguide optical splitter is too large, and the splitting angle is small, resulting in the occupation of 16 or more multi-channel splitters. The plane area is relatively large, the design and manufacture are difficult, and the size is too large. [0003] Chinese Patent Publication No. CN1467926, published on January 14, 2004, discloses a kind of optica...
