论文摘要
在本文中，通过级联几个双重光子晶体，我们证明，与隔离腔相比，质量因子可能要大得多，而不会增加设备的总尺寸。我们以Niobate光子晶体为例，以说明级联腔的模拟质量因子可以以70°倾斜的角度达到10^5，这是比孤立腔中大的数量级。该设备可以通过当前的Niobate锂蚀刻技术轻松制造。我们已经在实验上制造了提出的设备，其中包括具有70°倾斜角的孔。预计这项工作将为具有高质量因子的光子晶体腔设计提供指导。
In this paper, by cascading several bichromatic photonic crystals we demonstrate that the quality factor can be much larger compared with that in an isolated cavity without increasing the total size of the device. We take lithium niobate photonic crystal as an example to illustrate that the simulated quality factor of the cascaded cavity can attain 10^5 with a 70° slant angle, which is an order of magnitude larger than that in isolated cavity. The device can be fabricated easily by current etching technique for lithium niobate. We have fabricated the proposed device experimentally including holes with 70° slant angle. This work is expected to provide guidance to the design of photonic crystal cavity with high-quality factor.
