Description

Dynamic and large-scale user access through frequency switching in the terahertz (THz) band is highly anticipated. Previously, we demonstrated multi-level frequency modulation using THz frequency switching via photomixing with a tunable laser diode (TLD) and a fixed-frequency laser. Additionally, we proposed a compact THz generation method using a single TLD. In this study, we integrated these methods and demonstrated, for the first time, THz frequency switching in the J-band (220-330 GHz) using a single TLD. In the experiment, successful switching among three frequencies within the J-band was achieved using a high-speed TLD.
