We first synthesized a thin silica film encapsulated with condensed H aggregates of pseudisocyanine dyes (PIC) cyanine bromide dyes by a simple sol-gel method. The high optical nonlinearity (χ3=3.0 × 10-8 esu) of the film at the resonance wavelength ( = 436 nm) of the H aggregates was first observed by a Z-scan method using a 180-fs pulse laser. The net | χ(3) | value of pure H aggregates should be much larger than 3.0 × 10-8 esu according to the doping ratio of H aggregates in silica film.
