Abstract : A new class of all organic sol-gel second-order nonlinear optical (NLO) materials based on hexa(methoxymethyl)melamine (HMM) has been developed. Two NLO active chromophores, 4-(4'nitrophenylazo)aniline (DO3) and 4-amino-4'- nitrobiphenyl (ANB), were incorporated into the melamine matrices. The samples exhibit second-order optical nonlinearity after poling and curing at 220 deg C for 30 min. DO3/HMM and ANB/HMM samples show a second harmonic coefficient, d33 of 10.7 and 1.8 pm/V at 1064 nm, respectively. The temporal stability of both systems has been studied at room temperature as well as at 100 deg C. Waveguide optical losses of samples at 633 and 830 nm are reported.
