H. Nakayama et al., THERMALLY STABLE AND RESONANCE-ENHANCED LARGE NONLINEAR-OPTICAL PROPERTIES IN POLED SILICA FILMS DOPED WITH THIAZOLE AZO-DYE, Optical review, 2(4), 1995, pp. 236-238
Sol-gel processed poled silica films doped with novel nonlinear organi
c materials, thiazole azo dye (TA), are prepared in high concentration
. Resonance enhanced second-order nonlinear optical coefficient of d(3
3)=154 pm/V is obtained from TA doped silica film (40 wt%) for the fun
damental wavelength of 1064 nm. The value d(33) is unvaried for at lea
st 100 h under a high temperature condition (100 degrees C) without an
y relaxation. Wavelength dependent second-order nonlinearity is also m
easured.
