Abstract

The invention discloses a two-core optical splitter. The two-core optical splitter comprises a coupling fiber optic which is in butt joint with a target fiber optic and same with or similar to the target fiber optic in structure, wherein the coupling fiber optic is fixed on a first substrate and contacted with and fixed on one side of a double-line optical waveguide substrate; a first fiber core and a second fiber core in the coupling fiber optic are aligned with a first optical waveguide and a second optical waveguide of the double-line optical waveguide substrate; a first single core fiber optic and a second single core fiber optic are fixed on a second substrate and contacted with and fixed on the other side of the double-line optical waveguide substrate; and a third fiber core and a fourth fiber core of the first single core fiber optic and the second single core fiber optic in the coupling fiber optic are respectively aligned with the first optical waveguide and the second optical waveguide of the double-line optical waveguide substrate. According to the two-core optical splitter, two fiber cores of a two-core fiber optic can respectively conduct coupling and butt joint with independent fiber optics, respective output of optical signals transmitted in the two core through two single core fiber optics can be achieved, the two-core optical splitter is convenient to use, simple in structure, and low in cost, and has excellent application prospects.

Description

technical field [0001] The invention relates to an optical splitter, in particular to a double-core optical splitter. Background technique [0002] In recent years, multi-core fiber has been widely studied and gradually applied in the fields of communication, fiber laser and sensing, but the problems of multi-core fiber splicing and multi-core fiber-to-single-core coupling have not been completely solved. Although the output of the light transmitted in the multi-core fiber through the single-core fiber has been realized for many years, the beam splitting output of the multi-core fiber has not been realized, that is, the optical signal transmitted in each core of the multi-core fiber cannot be transmitted through multiple Independent optical fibers output separately. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings in the above-mentioned prior art and provide a dual-core optical splitter. The dual-core optical splitte...
