A new kind of thermo‐optic switch based on DR1/PMMA is proposed. This material has good cost‐performance, large thermo‐optic coefficient, and other advantages for electro‐optic devices because of the nonlinear chromophore DR1. Based on Mach‐Zehnder interferometer, this switch adopts the square waveguide structure and polymer silica hybrid configuration to adjust the optical field distribution for...
