Abstract: (1644 Views)
In this paper, the effect of temperature on the resistivity of the core and coating layers in the polymer electro-optic modulators has been investigated. In the polling process, the temperature of the material increases to glass temperature, which will reduce its electrical resistance. The clad material is selected so that the resistivity is at least 100 times lower than the core layer. Under these conditions, most of the electric field is on the core layer, which leads to an increase in the polling efficiency and the maximum modulation voltage is on the core layer. By adding 15% EDOT: PSS to the PVA, its resistivity is reduced by a hundred times and its dependence on the heat is also decrease.
