Application research of high performance photodetector

Abstract

Photodetectors can capture optical signals and convert them into electrical signals. As an important optoelectronic device, it has important application value in imaging, optical communication, security inspection, environmental monitoring and other fields. Silicon-based photonic integrated chips have unique advantages and play an important role in optical communication. Fabrication of high-performance detector arrays is the current research hotspot and frontier direction. Driven by high-speed communications such as big data, cloud computing, and 5G communication networks, the transmission rate and carrying capacity of data information continue to climb to super-large capacity and high-speed. Data transmission is upgraded to larger bandwidth and faster rate, and electrical interconnection is difficult to meet the demand for high-speed data transmission. In this paper, different kinds of high-performance photodetectors are analyzed, and the performance characteristics of several typical high-performance photodetectors are studied. Optical communication technology has the advantages of abundant spectrum resources, high security, and strong anti-electromagnetic interference ability. It can carry long-distance, large-capacity and high-speed data communication, and has become an important development direction in data center interconnection solutions. Data center is an important carrier for processing and computing Internet applications. This paper studies the application of high-performance photodetectors in visible light communication technology in combination with data center communication scenarios.
