D. Kundu et al., PREPARATION AND OPTICAL NONLINEAR PROPERTY OF SOL-GEL-DERIVED CU-SIO2THIN-FILMS, Journal of the American Ceramic Society, 77(4), 1994, pp. 1110-1112
Cu-metal-doped glass films having a Cu:Si atomic ratio of 0.05 +/- 0.0
02 were successfully prepared by a sol-gel method using a dipping tech
nique. The appearance of surface plasmon of Cu metal at about 570 nm w
as observed after heat treatment at or above 700-degrees-C. The third-
order nonlinear susceptibility (chi3) was as high as 5.0 x 10(-8) esu
at 570 nm.
