The nonlinear optical (NLO) active chromophore was prepared by a bridging agent, glycidyl ether(AGE), to connect disperse orange 3 ( DO3 ) and ( γ-Methacrylpropyl ) -silsesquioxane (MP-SSO). A freeradical polymerization was performed to fabricate the methacrylate/Silica hybrid NLO films. Different amounts(5-25 wt% ) of (γ-methacrylpropyl)-polyhedral oligomeric silsesquioxanes (POSS) were added as the modifier to improve the degree of cross-linking, density and structure of the NLO matrix. As a result, the modified material properties including coating transmittance, glass transition temperature ( Tg), absoption spectra before and after poling, Marker stripes, etc. were presented. The hybrid film containing 15 wt% POSS exhibits the highest Tg, nonresonant second-order nonlinearity (d33 = 92 pm/V) and temporal stability among the others.
