Плазмонний нанолазер: фізичні принципи роботи та галузі використання

Abstract

In recent years, a lot of research has focused on the development of new ultra-small lasers. The greatest progress has been made in the development of semiconductor lasers. A fundamentally new approach in miniaturization of lasers is the use of plasmonic fields instead of photonic fields. In contrast to photonic fields, plasmonic fields allow localization of light in sizes smaller than the diffraction limit of radiation, which in turn allows overcoming the diffraction limitation of reducing the laser dimensions down to several nanometers. The work discusses the basic physical principles of laser radiation generation using plasmonic fields, discusses the structure and characteristics of several types of plasmonic nanolasers, as well as their possible applications
