“…30 The resistivity of NLO polymer materials is typically on the order of 1 x i0' 2-cm. 4,7,8,22,35,36,[39][40][41][42][43][45][46][47][48][49] The resistivity of the cladding layers was made the variable and the voltage drop across the core layer was modeled as a function of resistivity of the cladding material.
