We developed a THz-TDS system using a chaotic light source constructed from a 650-nm semiconductor laser diode, and consequently demonstrated the generation of CW THz radiation with comb-like frequency spectrum and very narrow-spaced modes. Such a semiconductor chaotic laser-based measurement system with 0.025-THz resolution is highly promising for 5G and beyond 5G applications.
