Abstract
Here we demonstrate a 3X - 6X increase in the nonlinearity, or electro-optic (EO) coefficient, and a 40% - 85% increase in working device yield, 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. This has the potential to realize significantly higher EO coefficients without the need to synthesize new NLO polymer materials, as well as an increase in device yield due to less failure during poling.
