Abstract

We propose a method to extend the frequency range of polarization entanglement in periodically poled rubidium-doped potassium titanyl phosphate (Rb:KTP) waveguides. Our calculations predict that output wavelengths from 1130 nm to 1257 nm may be achieved using Rb:KTP by the appropriate selection of a direction of propagation for the waveguide. The fidelity using a poling period of 1 mm is approximately 0.98.

摘要

我们提出了一种方法来扩展周期性极化掺铷磷酸钛氧钾（Rb:KTP）波导中极化纠缠的频率范围。我们的计算预测，通过为波导适当选择传播方向，使用Rb:KTP可以实现1130纳米至1257纳米的输出波长。使用1毫米极化周期时的保真度约为0.98。
