    Second-harmonic generation in Langmuir-Blodgett waveguide overlays on single- mode optical fiber
    (Optical Society of America, 1999-09-30T00:00:00Z) Johal, S. S.; James, Stephen W.; Tatam, Ralph P.; Ashwell, Geoffrey J.
    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.
