论文摘要
我们从理论上研究了嵌入螺旋性的Fabry-Pérot腔中的手性分子的圆形二分法。我们发现分子的固有手学反应增加了2个数量级，并在进入强烈的轻度耦合方面时报告了手性空腔极性的第一个明确特征。我们研究了基于在狭窄频率范围内作用的两个介电光子晶体镜的腔设计，作为一个极化的有效极化交叉转换器，用于一个极化，几乎是另一个极化的几乎完美的反射器。我们表明，在这样的空腔内部托管的巴斯德介质可以有效地融入腔的外部和螺旋性耐螺旋性模式，从而继承了增强的手性特征。我们希望这种设备在将来有用，可以为光学和立体化学设计超敏感的手性传感器。
We theoretically study circular dichroism of chiral molecules embedded inside a helicity-preserving Fabry-Pérot cavity. We find an increase of the intrinsic chiroptical response of the molecules by 2 orders of magnitude and report the first clear signature of chiral cavity polaritons upon entering the regime of strong light-matter coupling. We study a cavity design based on two dielectric photonic crystal mirrors acting, in a narrow frequency range, as efficient polarization cross-converters in transmission for one polarization and almost perfect reflectors for the other polarization. We show that a Pasteur medium hosted inside such a cavity can couple efficiently to both the outside of the cavity and to the helicity-preserving mode, inheriting an enhanced chiral character. We expect such a device to be useful in the future to design ultrasensitive chiral sensors for optics and stereochemistry.
