Abstract

We observe carrier phase dependent generation of low-frequency spectral components in the near-field zone of a subwavelength aperture illuminated by subcycle far-infrared (terahertz) pulses. Diffraction induced π/2-phase shift of the pulse carrier results in the spectral intensity variation of the low-frequency components. The effect appears only if the pulse duration is shorter than the period of the carrier oscillation.
