We propose a broadband planar transition between an InP-based coplanar waveguide (CPW) and Si dielectric rod waveguide using a tapered-slot mode converter. The proposed planar transition yields broadband operation and is a promising technology for integrating photonic THz active devices with dielectric interconnects for future on-chip Tbps communication.
