Heater of polymetric thermo-optic switch based on analysis of the thermal field

First, the relationship between effective index change and thickness of cladding and substrate in thermo-optic switch is studied. Then, rectangle heater is simulated using the Beam Propagation Method. And a novel heater, arc heater, is designed. The thermo-optic switch using arc heater has better properties than using rectangle heater.
