Abstract
Creation of controllable narrow-band emission sources for the mid- and long-wavelength infrared ranges is one of the primary tasks of infrared technology. In this paper, we propose and demonstrate non-luminescent (thermal) magnetically controllable sources of infrared emission based on semiconductor magneto-optical photonic structures (MOPS). It is shown that interference effects cause narrow-band thermal emission spectrum of such sources, and magnetic field makes it possible to effectively control the spectral and amplitude characteristics of emissivity in the mid- and long-wavelength infrared range. Influence of the MOPS composition and design on the source emissive characteristics is studied. Using the obtained results, the designs of A3B5 semiconductor compounds based sources with dynamically tunable spectrum and amplitude modulation of emission are proposed. Theoretical modeling has shown the possibility of dynamic control of their emission parameters by achievable magnetic fields. Such sources may be used in environmental monitoring systems, medicine, forensics, infrared spectroscopy, etc.
