at 637 nm visible light, extending to near-infrared (940 nm) and short-wave infrared (1550 nm) regions. The vertical nanochannels enable low power consumption and voltage-tunable optical communication encryption functionality. This work provides a novel approach to overcoming the limitations of traditional lateral structures in speed and spectral response, advancing the development of miniaturized and multifunctional broadband high-speed photodetection technologies.
