In this work, we demonstrate a stimulated emission-controlled photonic transistor on a single organic triblock nanowire composed of alternate energy donor and acceptor. The population of acceptor excitons was engineered by energy transfer to achieve enhanced fluorescence, which was further amplified by the stimulated emission of the donor and the optical feedback in the nanowire microcavities, yielding a remarkable nonlinear amplification of the acceptor emission. On this basis, a prototype of photonic transistor with high nonlinear gain at very low pump energy was achieved. The results will provide a useful enlightenment for the rational design of novel all-optical switches with desired performances.

单个有机三嵌段纳米线上的受激发射控制光子晶体管

在这项工作中，我们在由交替的能量供体和受体组成的单个有机三嵌段纳米线上展示了受激发射控制的光子晶体管。通过能量转移设计受体激子群以实现增强的荧光，通过供体的受激发射和纳米线微腔中的光反馈进一步放大，产生显着的受体发射非线性放大。在此基础上，实现了在极低泵浦能量下具有高非线性增益的光子晶体管原型。结果将为合理设计具有所需性能的新型全光开关提供有用的启示。
