摘要

A light-induced index change and nonlinear absorption were clearly observed in channel optical waveguides fabricated from a novel quinoid dye, 4,8-dihydroxy-2,6-bis(butylamino)-1,5-naphthoquinone. The measured response time of the index change was below 10 ps, and the magnitude of the light-induced phase shift was more than 2 pi at the wavelengths of 780 and 800 nm in a 10-mm-long waveguide. The values of the nonlinear refractive index and the nonlinear absorption of the dye estimated from the experimental results are of the same order as that measured by the third-harmonic-generation method. This waveguide should lead to the construction of all-optical functional devices that have fast operating times. (C) 1998 Optical Society of America. [References: 16]
