Embodiment Construction

[0015] figure 1 is a schematic diagram of a specific embodiment of a low-crosstalk organic polymer waveguide optical switch according to the present invention. The device includes an input waveguide 11, a Mach-Zehnder interference waveguide structure 12, a first output waveguide 13, a second output waveguide 14, a first metal thin film thermode 15, a second metal thin film thermode 16, a third metal thin film thermode Electrode 17, polymer clad structure 18. The structure of the low-crosstalk organic polymer thermo-optic optical switch we designed selected materials with relatively large thermo-optic coefficients as the core and cladding materials of the waveguide. The thermo-optic coefficient of the core material is negative and the absolute value is large, and the thermo-optic coefficient of the cladding material is positive or the thermo-optic coefficient of the cladding material is negative, but the absolute value is small. The optical signal is input from the input wave...

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.
