Ultrafast Waveguide MUTC Photodiode Targeting Over 200 GBaud Applications at 1310 nm and 1550 nm

We demonstrate a waveguide integrated modified uni-traveling carrier (MUTC) photodiode designed for optical interconnects exceeding 200 Gbaud. It features an ultra-wide bandwith over 170 GHz, with responsivities of 0.52 A/W at 1550 nm and 0.35 A/W at 1310 nm.
