This project aims at the fabrication of periodically poled waveguide structures with ultrashort periods in lithium niobate and KTP for counter-propagating parametric down conversion. We will focus on the development of the technological processes required to achieve ultra short domain periods in a combined technological and analytical approach in close cooperation with theoretical materials physics. The realized structures will be investigated for the applicability in real PDC sources in terms of their nonlinear optical properties. Achieving counter-propagating parametric down conversion will enable bright and narrowband single photon sources necessary for novel quantum optical experiments.

本项目的目的是在铌酸锂和KTP中制造具有超短周期的周期性极化波导结构，用于反传播参数下转换。我们将专注于与理论材料物理学密切合作，以结合技术和分析方法实现超短域周期所需的技术过程的发展。根据所实现的结构的非线性光学特性，研究其在实际PDC光源中的适用性。实现反向传播参数下转换将使新型量子光学实验所需的明亮和窄带单光子源成为可能。
