“…[ 10 ] Currently, photodetectors mainly come in three types of configurations: photomultiplier tube (PMT), self‐powered photodetector (SPPD), and photoconductive devices (PCD). [ 11–16 ] Among them, PMTs utilize the photoelectric effect of photons and an electron cascade amplification mechanism to initiate electron emission on a photosensitive cathode, followed by a series of multiplication stages through photomultiplier tubes, exponentially amplifying the photocurrent signal to achieve high‐sensitivity light detection. They exhibit high sensitivity and fast response characteristics, but they have disadvantages such as high voltage operation, large size, and limited dynamic range.…”

Optical communication has become a research hotspot in modern non‐contact communication systems, and high‐performance photodetectors, as a key component, are crucial for achieving high‐fidelity signal transmission. Photoconductive devices (PCDs) are expected to find applications in the field of optical communication due to their advantages in high gain. However, it is difficult to achieve an effective balance between high responsiveness and fast response times in PCDs, leading to significant challenges in their commercial applications in the field of optical communication. In this paper, by employing both the mask method and channel width tuning method, a high‐performance PCD is developed based on the Ag‐MAPbI3‐Ag structure, demonstrating a high responsivity of 45.5 A W−1, a high detectivity of 7 × 1012 Jones, and a fast response time of 0.35 ms. Finally, this device is integrated into an optical communication system using embedded technology, effectively achieves byte transmission, and demonstrates the practical application of single‐crystal MAPbI3 PCD as a signal receiver in the system. This research provides a noteworthy approach to facilitating the seamless integration and commercialization of optical communication systems utilizing perovskite single‐crystal devices, while also paving the way for optical interconnects based on perovskite.

Photoelectric sensing technology plays a crucial role in vehicular equipment, which is equipped with various photoelectric devices to perceive the surrounding environment and avoid traffic lights and vehicles. This research selects the Hamamatsu H9500, a 256-channel, position-sensitive photomultiplier tube, as the test unit. It aims to simplify signal readout while improving the spatial resolution of the photodetector. This research focuses on designing a charge distribution circuit named Discretized Positioning Circuit (DPC) for the photomultiplier tube, with an additional charge-sensitive front-end amplification and shaping circuit. This circuit can convert the weak current signals from the H9500 into voltage signals. The shaping part of the circuit employs an active CR-RC circuit with weak signal amplification capabilities. This circuit is deployed within the photomultiplier tube, strategically positioned on vehicles to recognize various traffic sign images. The front-end shaping circuit is tested in the experiments, which converts square wave voltage into pulse current using a capacitor. It is observed that the current signal has a certain width and the voltage waveform of the CR differential circuit can be obtained by increasing the input impedance to 1 MΩ. During input voltage amplitude testing, the corrected output signal voltage shows a good linear relationship with the input square wave voltage. This designed front-end shaping circuit is used for signal readout in photomultiplier tubes and deployed in vehicular equipment to collect image information of traffic signs. After image processing, satisfactory recognition results are achieved.
