Second-harmonic radiation has been obtained from Langmuir-Blodgett films of E-N -octadecyl-4-[2-(4-dibutylaminophenyl)ethenyl]quinolinium octadecylsulfate, deposited as a waveguide overlay upon optical fiber that is single mode at the pump wavelength (lambda=1064 nm) . A quadratic relationship between the pump power and second-harmonic intensity was observed.
