Abstract
The waveguide design and second harmonic generation experiment within inverted and non-inverted waveguides is discussed. The effect on phase-match and overlap integral, of an interlayer having different refractive index into the core region of the waveguide is investigated. The experimental waveguide is made of two identical Langmuir-Blodgett films with 2-docosylamino-5-nitropyridine. Both thin films and waveguide characterisation are presented including a detailed description of the experimental set-up. An inverted waveguide is produced by a proper arrangement of the thin organic films. With a tunable laser source, phase-matching of SHG is proven.
