Abstract:
Organic waveguides are well suited for second harmonic SH generation. We present here experimental results of SH generation from a polyurethane waveguide spin-coated on a silver grating coupler. As one of the waveguide boundaries is made from a metal it is possible to excite, in addition to guided modes, a surface plasmon SP at this boundary. We investigate the angular dependence of the SH generation from the polyurethane coated grating. The excitation of the electromagnetic resonances at the pump frequency lead to a large increase of the diffracted SH light intensity. In order to study the wavelength dependence of the SH efficiency, we have employed two pump wavelengths 1064 nm and 1318 nm. For the shorter wavelength pump, the SH falls within the absorption band of the polymer.
