Abstract: The conditions for amplification and modulation of electromagnetic radiation during its interaction with a space charge wave formed in a semiconductor cylindrical structure are considered. The possibility of implementing the resulting gain G > 105 m–1, as well as strong phase modulation (chirp) for wave packets propagating on the surface of a semiconductor cylindrical waveguide, is shown. A ring laser scheme is proposed that is capable of generating frequency-modulated subnanosecond pulses with a peak power of over 1 kW and a carrier frequency tunable over a wide spectral range.

Keywords: semiconductor cylindrical waveguide, space charge wave, phase modulation, generation of frequency-modulated pulses.
