Spectra of Wideband Dipole Radiation Induced by the Photomagnetoelectric Response in Narrow Gap Semiconductors

Title variants
Languages of publication
The frequency spectra of sign inverted photomagnetoelectric responses in narrow gap semiconductors InSb, InAs, and Cd_{0.2}Hg_{0.8}Te, excited by nanosecond laser light pulses, were used for calculation of induced electromagnetic radiation frequency spectra in dipole approximation. The parallelepiped shape sample was considered as capacitor-like point dipole. The known Fourier transform property was used in calculations. Features of double sign inverted signals formation and its spectra are considered and compared with experimental results. The radiation of pulses, having spectra in terahertz range when excited by picosecond laser pulse from capacitor-like radiators that demonstrate double sign inverted photoresponses, is expected.
