“…Optical MRs being bodies of rotation (spheres, disks, rings) are known to support so-called WGMs, which are characterized by large azimuthal numbers, and their electromagnetic field antinodes are located near the edge of the structure. Due to the high quality factor of the WGMs, resonators of this type can be used in optics to create lasers with a low threshold [9,10] and photon generators [11], for detecting single atoms in magnetic traps [12], as well as in quantum information science as containers for optically active QD qubits [13][14][15]. In [16], an example of implementation of one-and two-qubit quantum operations caused by the exchange of an energy quantum between a semiconductor QD and one of the microdisk WGMs is given.…”

A spectroscopic method for determining the number of electrons in a quantum dot (QD) located inside a microdisk resonator is proposed. A transducer with the form of a ring structure composed of single-electron QDs is an auxiliary element used to enhance the interaction of laser photons with the QD and with the microdisk. The microdisk parameters are calculated to ensure an efficient energy exchange between the disk modes and the transducer QDs. The influence of the Stark and Förster effects on the measurement accuracy is studied. The optimal measurement regime is shown to be achieved provided that both effects are compensated.

“…Thus, the use of the MR allows one to adjust the number of photons generated by the QD. Today, there are well-developed technologies for manufacturing high-quality MRs of various types [6][7][8]. These are MRs supporting whispering gallery modes, layered Bragg structures and microcavities (MCs) based on defects in photonic crystals (PCs).…”

A scheme for the photon generation induced by the electron optical transition in a semiconductor structure consisting of a quantum dot and two quantum wells is proposed. A nanobeam photonic crystal microcavity is used as a source of the driving field and for concentrating the electromagnetic energy emitted during the cascade transport of electrons. We calculate the population dependences of the electron and microcavity Fock states as well as the average number of photons (a radiation power) on time, a mode decay rate and electron tunneling rates between the quantum dot and metal contacts. The generation power is shown to be root-dependent on the tunneling rates, and the maximum generation power is limited by the photon dissipation rate.

We consider an ordered array of semiconductor singleelectron quantum dots located in the antinode of a mode of a microcavity based on a two-dimensional photonic crystal. The influence of Coulomb effects on the energy exchange between quantum dots and the mode is studied in arrays for different numbers of dots. The stability of resonant electron – photon dynamics is analysed as a function of technological deviations of the dot parameters caused by the imperfection of the manufacturing procedure. Using the data of numerical simulation of the spectroscopic response of the system, criteria are formulated for using such a structure as a detector of localised charges. The parameters of the photonic crystal are chosen, which make it possible to implement the proposed measurement scheme.
