Organic nonlinear optical (NLO) materials have attracted much interest for their potential applications over the past two decades mainly because of their faster electronic response and larger optical nonlinearities than the conventional inorganic materials. Especially, electro-optic (EO) polymers have been promising candidates for fast and broadband EO modulators as a result of the development of the 2nd-order NLO chromophore. In this manuscript, we report fabrication and design of one dimensional (1D) polymeric photonic crystals (PCs) to additionally enhance the optical nonlinearities of the organic NLO materials. We fabricated polymeric high-reflection mirrors for 1D PCs by a simple alternatively spin-coating two polymers under control of their optical thickness, in which a novel polymer was applied to the higher refractive index layer. We also designed defect-mode 1D polymeric PC for effective light-localization in the defect layer and discussed their effect for enhancement of the 2nd-order optical nonlinearities.
