In optical fiber communication systems, as the transmission rate increases, the traditional O/E/O relay method can no longer meet our needs, and the semiconductor optical amplifier can directly perform optical/optical conversion. Semiconductor optical amplifiers are mainly optical amplifiers made of semiconductor materials. The rapid development of semiconductor optical amplifiers mainly benefits from the successful development of quantum well materials semiconductor optical amplifiers, which overcomes the disadvantage of polarization sensitivity. The development and use of quantum dot materials can improve the transmission efficiency and waveform stability of semiconductor optical amplifiers, and optimize the performance of noise and crosstalk. This topic is mainly based on semiconductor lasers. It introduces the principle and structure of semiconductor optical amplifier, the development process, and the basic functions and applications of semiconductor optical amplifiers. In addition, the latest domestic and foreign developments of semiconductor optical amplifiers are also discussed. The semiconductor optical amplifier can directly amplify the optical signal, and has a high degree of transparency to the signal format and rate, making the entire system simple and flexible. Its appearance and practicality is a milestone in the history of optical fiber communication.
