摘要：

Second-harmonic generation by excitation of guided modes and the surface plasmon in a polyurethane-coated silver grating coupler is presented. In order to study the spectral dependence of the second-harmonic efficiency, two different pump wavelengths are used, 1064 and 1319 nm. For the longer-wavelength pump we observe a large enhancement of the second-harmonic efficiency as the incident angle is scanned through an electromagnetic resonance, whereas for the shorter-wavelength pump the second-harmonic wavelength falls within the absorption band of the polymer, and we observe unexpected minima instead of maxima.
