摘　　要：在光纤通信系统中,随着传输速率的增加,传统的O/E/O中继方式已经不能满足我们的需求,而半导体光放大器可以直接进行光/光的转换。半导体光放大器主要是一种由半导体材料制造的光放大器,半导体光放大器的快速发展主要得益于量子阱材料半导体光放大器的研制成功,克服了偏振敏感的缺点。而量子点材料的研发和使用可提高半导体光放大器的传输效率和波形稳定性,并且使噪声和串扰性能更加优化。本题主要是以半导体激光器为基础,介绍了半导体光放大器的原理和结构、发展历程,以及半导体光放大器的基本功能和应用。另外还探讨了半导体光放大器的最新国内外进展。半导体光放大器能直接放大光信号,对信号的格式和速率具有高度的透明性,使得整个系统更加简单灵活,它的出现和实用化在光纤通信发展史上具有里程碑意义。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.
