Embodiment 1
[0021] The invention comprises an input waveguide (1), at least two output waveguides (2), (6), at least one coupling region (7) and a bent waveguide (9), wherein the coupling region (7) is arranged on the input waveguide (1 ) and the output waveguide (2), (6), the entrance port of the coupling area (7) is connected with the input waveguide (1), and the exit port of the coupling area (7) passes through the bending waveguide (9) and the output waveguide respectively (2) and (6) are connected to form a 1×2 power splitter.
Embodiment 2
[0023] On the basis that Embodiment 1 has two output waveguides (2), (6), the present invention is also provided with an output waveguide (4) in the forward propagation direction of the straight waveguide (1) of the above-mentioned input waveguide (1), forming a 1 × 3 power splitters, such as figure 2 shown.
Embodiment 3
[0025] On the basis that Embodiment 1 has two output waveguides (2), (6), the present invention is also provided with a coupling area (8) behind the coupling area (7), and the entrance port of the coupling area (8) is connected to the input The waveguides (1) are connected, and the exit ends of the coupling area (8) are respectively connected to the output waveguides (3) and (5) through the bent waveguides (9), forming a 1×4 power splitter.
