Special phase matching of SHG using photonic effect has been experimentally confirmed for an obliquely propagating fundamental beam in the helical smecfic-C*(SmC*) liquid crystal phase, as suggested by Belyakov(JETP Lett, 70, 811(1999)). The enhancement of SHG occurs when SH wave is close to a photonic gap(half-pitch band) and consequently fundamental wave is also close to another photonic gap(full-pitch band). The enhancement signal was observed both from transmitted and reflected directions, and was compared with our simulation developed recently.
