Abstract
We propose a method to extend the range of polarization entanglement in periodically poled rubidium- doped potassium titanyl phosphate (Rb:KTP) and titanium in-diffused lithium niobate (Ti:LN) waveguides. By fabricating waveguides at an angle relative to the crystal axes, output wavelengths near 1130 nm to 1257 nm may be achieved using Rb:KTP and 1858 nm to 2254 nm using Ti:LN. The fidelity using a poling period of 1 mm is approximatley 0.98.Citation
