Abstract

Waveguide strategies of phase-matching secondharmonic generation in nonlinear organic materials are examined. The mismatches of propagation constants of guided modes in planar waveguides are expressed through waveguide parameters, and the ability of multimode waveguides to phase-match nonlinear-optical processes in organic materials is assessed. The mismatch of propagation constants of the TE4/TM4 mode of the second harmonic and the TE0/TM0 mode of the pump field as a function of the size of the waveguiding layer with n(p)(w) = 1.50 and n(P)(2w) = 1.55 (solid line), 1.60 (dashed line), and 1.65 (dash-dotted line). The pump wavelength is I pm.
