Electrically controlled photonic circuits hold promise for information technologies with greatly improved energy efficiency and quantum information processing capabilities. However, weak nonlinearity and electrical response of typical photonic materials have been two critical challenges. Therefore, hybrid electronic-photonic systems, such as semiconductor exciton polaritons, have been intensely investigated for their potential to allow higher nonlinearity and electrical control, with limited success so far. Here we demonstrate an electrically gated waveguide architecture for field induced dipolar polaritons that allows enhanced and electrically controllable polariton nonlinearities, enabling an electrically tuned reflecting switch (mirror) and transistor of the dipolar polaritons. The polariton transistor displays blockade and antiblockade by compressing a dilute dipolar-polariton pulse exhibiting very strong dipolar interactions. The large nonlinearities are explained using a simple density-dependent dipolar polarization field that very effectively screens the external electric field. We project that a quantum blockade at the single polariton level is feasible in such a device.

具有巨大非线性度的场感应偶极化子的电控光子电路

电控光子电路为信息技术带来了前景，大大提高了能源效率和量子信息处理能力。然而，典型光子材料的弱非线性和电响应一直是两个关键挑战。因此，人们深入研究了混合电子光子系统，例如半导体激子极化激元，以了解它们在实现更高非线性和电气控制方面的潜力，但迄今为止的成功有限。在这里，我们演示了一种用于场感应偶极化激元的电门控波导架构，该架构允许增强和电控的极化激元非线性，从而实现偶极化激元的电调谐反射开关（镜子）和晶体管。极化激元晶体管通过压缩表现出非常强偶极相互作用的稀释偶极化激元脉冲来显示阻断和抗阻断。使用简单的密度相关偶极极化场来解释较大的非线性，该场非常有效地屏蔽了外部电场。我们预计，在这种装置中，单个极化激元水平的量子封锁是可行的。美国物理学会 2024 年出版
