The problem of calculating the probability of the process of recombination radiation and the spectrum of emitted photons in thin quantum filaments in a longitudinal electric field is solved in this work. It is known that the purest spectrum of recombination radiation is produced by quantum dots, since the motion of quasi-particles in them is limited in all three directions. Quantum wires have one classical degree of freedom. But the spectral and orientational properties of radiation after single-photon recombination in them have a number of significant advantages over quantum dots. It has been established that the spectrum of single-photon recombination in a thin quantum wire in a longitudinal electric field is purely monochromatic, despite the possibility of classical motion of quasi-particles. Moreover, the emitted photon can only move along the thread in one of two directions. It is shown (on the basis of the semiclassical approach) that quasi-particles in a wire in an electric field move with uniform acceleration. Scattering by phonons and impurity centers is strongly suppressed due to the energy gap in the transverse motion spectrum. The recombination process is localized at two points of the wire, where the dispersion relations for the emitted photon are satisfied. The photon frequency increases linearly with the field strength, and the recombination probability depends on it in a complex «oscillatory» way. This shows the theoretical possibility of creating highly efficient compact (without special focusing optics, etc.) monochromatic frequency-tunable emitters based on quantum wires.
