Ultrafast high response waveguide MUTC photodetector for optical-to-microwave conversion
We demonstrate waveguide Modified Uni-Traveling-Carrier (MUTC) Photodetectors (PDs) to complete optical-tomicrowave conversion. Ultra-high 3-dB bandwidths of 137GHz and 163GHz, high responsivities of 0.32A/W and 0.24A/W, and low dark currents of 3nA and 5nA have been achieved for 5×12μm<sup>2</sup> and 5×8μm<sup>2</sup> devices, respectively. These PDs demonstrate promising performance for photodetection of high-repetition-rate optical pulses, laying the foundation for the photonic chip-based ultra-stable and low-phase noise microwave generation.
