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

摘要

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 thepump wavelength (lambda = 1064 nm). A quadratic relationship between the pumppower and second-harmonic intensity was observed.
