We present a first-principles method to compute radiation properties of ultra-high quality factor photonic crystal cavities. Our Frequency-domain Approach for Radiation (FAR) can compute the far-field radiation pattern and quality factor of cavity modes ~ 100 times more rapidly than conventional finite-difference time domain calculations. We explain how the radiation pattern depends on the perturbation used to create the cavity and on the Bloch modes of the photonic crystal.
我们提出了一种用于计算超高品质因子光子晶体腔辐射特性的第一性原理方法。我们的频域辐射方法(FAR)计算腔模的远场辐射模式和品质因子的速度比传统的时域有限差分计算快约100倍。我们解释了辐射模式如何取决于用于创建腔体的微扰以及光子晶体的布洛赫模式。
