基于不同空间模式之间的相互作用，半导体布拉格反射波导（brw）为非线性光学提供了一个功能强大的平台。为了实现任何期望的量子光学功能，我们必须控制和设计每个空间模式的特性。为了达到这个目的，我们扩展了Fabry-Perot技术，并实现了色散多模半导体波导的详细线性光学表征。利用这种高效的宽带频谱方法，我们可以直接实验获得我们的brw的相关模式并确定它们的群速度。此外，我们表明我们的波导具有低于预期的损耗系数。这使得它们适合集成量子光学应用。
Based on the interaction between different spatial modes, semiconductor Bragg-reflection waveguides (BRWs) provide a highly functional platform for non-linear optics. For achieving any desired quantum optical functionality, we must control and engineer the properties of each spatial mode. To reach this purpose we extend the Fabry-Perot technique and achieve a detailed linear optical characterization of dispersive multimode semiconductor waveguides. With this efficient broadband spectral method we gain direct experimental access to the relevant modes of our BRWs and determine their group velocities. Furthermore, we show that our waveguides have lower than expected loss coefficients. This renders them suitable for integrated quantum optics applications.
