Ma. Khalil et al., Modal dispersion phase-matched frequency doubling in composite planar waveguide using ion-exchanged glass and optically nonlinear poled polymer, OPT COMMUN, 170(4-6), 1999, pp. 281-284
We report on the fabrication and characterization of composite planar waveg
uides for frequency doubling. Modal dispersion phase matching is obtained f
or TM, fundamental and (TM1, TM2) harmonic wavelength. The experimental con
version efficiency was eta = 0.45% with an SH wavelength of 0.516 mu m for
TM0omega-TM22 omega mode conversion. The phase-matching condition can be fu
lfilled by adjusting the diffusion time of ion-exchange and the thickness o
f the polymer layer. (C) 1999 Elsevier Science B.V. All rights reserved.
