Abstract. The coherent thermal radiation from semiconductor plane-parallel resonator
structures is investigated both theoretically and experimentally. The coherent properties
of thermal radiation from these objects are manifested by sharp spectral lines and well-
pronounced lobe-like directional patterns. We investigated the dependences of the
intensities of spectral lines and the angular distribution of thermal radiation on optical
parameters of the structures. New optical effects are presented, namely, the modulation
of the coherent thermal radiation spectrum by an external magnetic field and a uniaxial
pressure.
Keywords: thermal radiation, coherent radiation, plane-parallel structure, IR emitter.
