摘　　要：We have designed and fabricated zero-bias operational two-element symmetric-connected photodetector arrays(SC-PDAs).The designed SC-PDAs have higher saturation currents,larger RF power,and better frequency responses than the single photodetector(PD)under zero bias.The bias-free SC-PDA with 15μm diameter of each PD demonstrated a 3 d B bandwidth of 19.4 GHz at 0.5 m A.The RF saturation photocurrent and maximum RF output power of the SC-PDA with 40μm,50μm,and 60μm diameters under zero bias are over9.31 m A and-5.86 d Bm at 3 GHz,14.52 m A and 1.17 d Bm at 1 GHz,and 13.72 m A and-1.76 d Bm at 1 GHz,respectively.
