Abstract
In our previous work we demonstrated a 3X increase in the nonlinearity, or electro-optic (EO) coefficient of the nonlinear optic (NLO) polymer disperse red 1:Polymethylmethacrylate (DR1: PMMA) by introducing a thin guanine nucleobase interfacial buffer layer, deposited between the NLO polymer and the cathode and a thin bathocuproine (BCP) interfacial buffer layer, deposited between the NLO polymer and the anode, being poled at 100 V/μm. In addition, we observed a 40% increase in EO coefficient by depositing either a thin sol-gel derived titanium dioxide layer or a thin guanine layer on either the anode or cathode side of the structure, poling at 100 V/μm. This paper addresses our analysis of these differences and is based on surface resistance.
