Abstract:
We present in this Letter the experimental generation of linear frequency modulated (LFM) terahertz pulses with large bandwidths by using an optical interferometer-based photonic scheme and cutting-edge terahertz transceiver technology. The LFM pulses exhibiting a bandwidth in excess of 60 GHz centered at 350 GHz are successfully generated in the experiment, which represents the first demonstration of large time-bandwidth products (TBWPs) in the terahertz region above 300 GHz, to the best of our knowledge. The achieved TBWP of up to 527 has great potential in many prospective applications such as high-resolution radar sensing and imaging.
