Abstract : KTP crystals, characterised by superior properties, are used widely in nonlinear optics, in particular for second harmonic generation. Also, owing to easy fabrication technology of low loss optical waveguides (approx. 1dB/cm), the KTP crystals are used for the fabrication of integrated optical elements. The important advantage of waveguides in KTP (for example, in comparison with that in the more widely used Ti:LiNbO3.) is the high optical damage resistance, up to 0.9W more light power in visible range. These properties of KTP give the possibility of designing some of the integrated optical elements for optical signal processing systems, particularly waveguided acousto-optical modulators and deflectors, using the surface acoustic waves (SAW) and optical waves interaction. Recently, the direct SAW excitation in KTP crystal by means of interdigital transducers (IDT) has been demonstrated.
