Anisotropy photoresponse can be effectively achieved based on gradient organic heterojunction. However, the gradient heterojunction has yet been studied due to the complicated process and great random error inside. Especially in the field of transient optics, the light on/off in femto/picosecond range is vitally important for high-speed optical systems, such as application in fiber communications. In this paper, the wedge-structured organic heterojunction was fabricated based on molecular beam epitaxy. The devices were combined with both wedge-structured heterojunction and half-wave plate. When the probe light was tuned to 2.0 eV, a narrow passband was instantly observed once the pump and probe light were perpendicular to each other. The photoresponse can be achieved within 0.84 ps which can tune the optical signals on and off in transient optics. The results have demonstrated an exciting application in photo sensing.
