Second-harmonic generation in Langmuir-Blodgett waveguide overlays on single- mode optical fiber

By S. S. Johal, Stephen W. James, Ralph P. Tatam and Geoffrey J. Ashwell

Abstract

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
