Abstract: Photonic integrated circuits (PICs) offer a great potential for THz systems. This work reports on the realization of optically pumped on-chip THz mixers using InP-based modified unitraveling-carrier photodiodes (MUTC-PDs) monolithically integrated with fermi-level managed barrier diodes (FMBDs). Ultra-broadband mixing up to 300 GHz is successfully demonstrated by providing sufficient LO power in form of the integrated waveguide-type MUTC-PD. Minimal conversion losses of 16.5 dB and a small NEP of 3.8 pW/√Hz are obtained at 30 GHz.
