Abstract

We propose a novel type of chromophore, naphthoquinone methide dyes, for nonlinear optics used in the near IR wavelength. The large resonance effect and the small intermolecular interaction allows the chromophore to show a large Pockels coefficient at 1.3 micrometers when it is poled in a polymer matrix. The origin of the nonlinearity is discussed by measuring the ground state dipole moment and the change in dipole moment between the ground and excited states. The polyurethane to which this dye was chemically attached was synthesized and the large nonlinearity was demonstrated. In polymer films, propagation loss at 1.3 micrometers increases maybe due to the aggregation of chromophores.
