waveguide switch
A multimode interference polymer-silica hybrid waveguide 2 2 thermo-optic switch free download A polymer-silica hybrid 2 2 thermo-optic switch is demonstrated. The top cladding and core layer are composed of polymers, while the bottom cladding is made of silica. Since polymer and silica have opposite signs of thermo-optic coefficients, the change of the refractive index […]
