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