The research and fabrication of the Y-branch optical waveguide switch is performed by using the thermo-optic effect of the organic polymer material. The experimental results show that the optical switch has a crosstalk of less than -20 dB and the driving power is 110 mW-130 mW. At the same time, the test results of insertion loss are given and the various causes of the insertion loss are analyzed. For the switching speed of the device, put forward a solution
