Abstract

The invention discloses a low-crosstalk organic polymer waveguide switch and relates to a low-crosstalk termooptical waveguide switch device. All waveguide structures are embedded in a cladding (18). The input end of a Mach-Zehnder interference waveguide structure (12) is connected with the output end of an input waveguide (11). Two output ends of the Mach-Zehnder interference waveguide structure (12) are connected with the input end of an output waveguide (13) and the input end of an output waveguide (14) respectively. The top of the Mach-Zehnder interference waveguide structure (12) is provided with a first metal membrane thermode (15). The top of the output waveguide (13) is provided with a second metal membrane thermode (16). The top of the output waveguide (14) is provided with a third metal membrane thermode (17). The device controls the first metal membrane thermode (15) and the second metal membrane thermode (16) through current respectively or controls the first metal membrane thermode (15) and the third metal membrane thermode (17) through current respectively to realize a low-crosstalk optical switch function.
