In 1985 Fridriech and Wintgen proposed a mechanism for bound states in the continuum based on full destructive interference of two resonances which can be easily applied to the two- and three-dimensional wave systems. Here we explicitly show that this mechanism can be realized in one-dimensional quantum potential well, owing to destructive interference of electron paths with different spin in tilted magnetic field. Due to one-by-one correspondence between the spin of the electron and the polarization state of light, we have found numerous bound states in the continuum in the one-dimensional photonic system and experimentally confirmed them. The experimental set-up consists of the one-dimensional photonic crystal conjugated with a liquid-crystalline anisotropic defect layer and covered by metal film.

连续体中的一维光子束缚态

1985年Fridriech和Wintgen提出了一种基于两个共振的完全破坏性干涉的连续态束缚状态的机制,可以轻松地将其应用于二维和三维波系统。在这里,我们清楚地表明,由于倾斜磁场中具有不同自旋的电子路径的相消干涉,该机制可以在一维量子势阱中实现。由于电子的自旋与光的偏振态一一对应,我们在一维光子系统的连续体中发现了许多束缚态,并通过实验加以证实。实验装置由一维光子晶体与液晶各向异性缺陷层共轭并覆盖有金属膜组成。
