Cerenkov-type second harmonic generation in a novel waveguide structure device has been investigated by using nonlinear organic material with grating couplers for the first time. The device has an isotropic waveguide layer with a grating coupler on an organic nonlinear crystal MNCZ (methyl-3-(p-nitrophenyl)carbazate) as a substrate of a slab type waveguide. The grating coupler was fabricated by two-beam holographic interference method whose period was 488 nm. Strong second harmonic generation (532 nm) was observed by grating coupler with fundamental wave, Q-switched Nd-YAG laser (1064 nm) at 36.5°.
