| Abstract: | Guided-wave second-harmonic generation using a passive planar waveguide covered with an organic nonlinear optical film as thin as a single molecular layer is demonstrated. The phase-matching condition of this process is revealed both with a high degree of waveguide-mode selectivity and a maximum in the frequency response. |
