Due to their nonlinear optical and dispersive properties, periodically poled (PP)-KTP waveguides are very attractive for photon pair generation and nonlinear frequency conversion. Especially, Rb-K-ion exchanged waveguides have gained considerable attention due to low loss guiding in both, TE- and TM-polarization thus even allowing for type-II quasi-phasematching. However, the doping dependent ionic conductivity of Rb:KTP makes periodic poling a challenging task.

We will discuss the control of the field-assisted poling process by optical monitoring and show first results of periodically poled channel waveguides. And finally, linear and nonlinear optical characterizations of these guides will be presented.
