Continuous-wave laser generation of slow THz surface plasmons in an array of single-walled carbon nanotubes

The mechanism of generation of surface plasmon polaritons in the THz and far-IR ranges by laser irradiation of arrays of single-walled carbon nanotubes is considered. It is shown that by varying the angle of incidence of the laser beam, one can change the frequency of generated surface plasmon polar...

Description
Summary:The mechanism of generation of surface plasmon polaritons in the THz and far-IR ranges by laser irradiation of arrays of single-walled carbon nanotubes is considered. It is shown that by varying the angle of incidence of the laser beam, one can change the frequency of generated surface plasmon polaritons. As consequence, the nanotube length can be matched to the laser wavelength for efficient conversion of cw laser radiation to the THz range.
