The scheme of a single-photon transistor formed by an array of semiconductor single-electron quantum dots in an optical resonator is considered. The spectral response of such a transistor depends on the Coulomb interaction of the electrons of the array with the electron at the measured quantum dot. An approximate analytical expression is obtained for the response function of a transistor with an arbitrary number of quantum dots. Using a one-dimensional array (chain) as an example, the dependences of the transistor response on the chain period, on the distance to the measured quantum dot, and on the degree of compensation for Coulomb effects are analysed. It is shown that the electron – photon dynamics of the transistor is substantially affected by the Frster effect, the suppression of which by alternating quantum dots with different symmetry of the excited state significantly increases the measurement accuracy.

考虑了由光谐振腔中的半导体单电子量子点阵列形成的单光子晶体管的方案。这种晶体管的光谱响应取决于阵列电子与被测量子点处电子的库仑相互作用。得到了具有任意数量量子点的晶体管的响应函数的近似解析表达式。以一维阵列（链）为例，分析了晶体管响应对链周期、到被测量子点的距离以及库仑效应补偿程度的依赖性。结果表明，晶体管的电子-光子动力学受弗斯特效应的影响很大，
