“…3 (a). The mode converter is excited by a ground-signal-ground (GSG) probe, and the output from the Si taper is detected by another THz coupler (V-coupler) [7], fabricated on a commercial substrate. First, we measured the response of the V-coupler in a back-to-back configuration for reference.…”

We demonstrate a broadband terahertz coupling between InP-based coplanar waveguide and silicon dielectric rod waveguide for hybrid integration. A coupling efficiency of around -2 dB has been experimentally achieved in frequency range between 70-120 GHz. Numerical simulations reveal an operational 3dB-bandwidth >100 GHz. Fig. 4. Measured coupling efficiency of the fabricated coupler between 60 to 90 GHz (green) and between 90 to 120 GHz (red). The black line represents the simulated coupling efficiency using CST Studio Suite. According to simulations, the 3dB-bandwidth exceeds 100 GHz.
