激子-极化激元介导的全光路由器

An exciton-polariton mediated all-optical router

H. Flayac, I. G. Savenko

摘要:

提出了一种基于周期调制波导双势垒门的全光非线性路由器。半导体微腔在势垒之间被非共振驱动,以在受到激子蓝移的离散态上形成激子-极化激元凝聚体。随后的相干光信号被允许通过波导传播,只要凝聚能量与微带谐振,或者如果它面对间隙则被阻挡。当对称样品作为光开关工作时,其非对称对应物体现为在施加磁场下变成偏振选择性的路由器。

英文摘要:

We propose an all-optical nonlinear router based on a double barrier gate connected to periodically modulated guides. A semiconductor microcavity is driven nonresonantly in-between the barriers to form an exciton-polariton condensate on a discrete state that is subject to the exciton blueshift. The subsequent coherent optical signal is allowed to propagate through a guide provided that the condensate energy is resonant with a miniband or is blocked if it faces a gap. While a symmetric sample operates as an optical switch, its asymmetric counterpart embodies a router turned to be polarization selective under applied magnetic field.
