Abstract

The carrier frequency of the modern telecommunication system had been raised to hundreds of GHz and aimed at the THz regime. Besides, THz waves have been intensively applied in many fields, e.g., spectroscopy, imaging, and communications. However, there is a rarity of available techniques for modulating few-cycle THz waves on picoseconds timescale. Here we report a simple/reliable system without spatial light modulators (SLMs) for generating circularly polarized THz dual pulses with variable helicity, frequency, and interval. These degrees of freedom allow us to arbitrarily control the THz double pulses of interests, which have potential applications in imaging, spectroscopy, and next-generation communications.
