Abstract
Phase-matched polarization in a polymeric waveguide induced by an all-optical poling technique was investigated. We fabricated the polymeric waveguide on a quartz substrate by casting from a chloroform solution of poly(methyl methacrylate) with 1,4-bis(2-{4--di(p-tolyl)amino]phenyl}vinyl) benzene (BTAPVB). The waveguide film was found to have no absorption at either the fundamental (1064 nm) or the second-harmonic (532 nm) wavelengths. We observed that the induced second-harmonic intensity has a quadratic dependence on the propagation length. This quadratic dependence suggests that the phase-matched polarization was formed along the direction of the beam propagation. The analysis of tensor components supports the fact that BTAPVB possesses an octupolar component in addition to a dipolar one.
