In this paper, we find that utilizing the resonance of photodiode with a collector can lead to a flat frequency response within the terahertz frequency range. To enhance the resonant peak output power, we propose a large-sized terahertz band photodiode (TB-PD) features a depleted absorption layer made of 400 nm InGaAs material. Operating under a bias of -4 V and an optical intensity of 1.5e5 W/cm2, the 20-µm-diameter TB-PD exhibits a 3dB flatness in the frequency range of 275 GHz ~ 437 GHz and − 4.6 dBm@340GHz of the output power.
