The 1550 nm band semiconductor optical amplifier (SOA) has great potential for applications such as optical communication. Its wide-gain bandwidth is helpful in expanding the bandwidth resources of optical communication, thereby increasing total capacity transmitted over the fiber. Its relatively low cost and ease of integration also make it a high-performance amplifier of choice for LiDAR applications. In recent years, with the rapid development of quantum-well (QW) material systems, SOAs have gradually overcome the shortcomings of polarization sensitivity and high noise. The research on quantum-dot (QD) materials has further improved the noise characteristics and transmission loss of SOAs. The design of special waveguide structures-such as plate-coupled optical waveguide amplifiers and tapered amplifiers-has also increased the saturation output power of SOAs. The maximum gain of the SOA has been reported to be more than 21 dB. The maximum saturation output power has been reported to be more than 34.7 dBm. The maximum 3 dB gain bandwidth has been reported to be more than 120 nm, the lowest noise figure has been reported to be less than 4 dB, and the lowest polarization-dependent gain has been reported to be 0.1 dB. This study focuses on the improvement and enhancement of the main performance parameters of high-power SOAs in the 1550 nm band and introduces the performance parameters, the research progress of high-power SOAs in the 1550 nm band, and the development and application status of SOAs. Finally, the development trends and prospects of high-power SOAs in the 1550 nm band are summarized.
1550纳米波段半导体光放大器（SOA）在光通信等应用领域具有巨大潜力。其宽增益带宽有助于扩展光通信的带宽资源，从而增加通过光纤传输的总容量。其相对较低的成本和易于集成的特点也使其成为激光雷达应用中高性能放大器的首选。近年来，随着量子阱（QW）材料系统的快速发展，SOA逐渐克服了偏振敏感性和高噪声的缺点。对量子点（QD）材料的研究进一步改善了SOA的噪声特性和传输损耗。特殊波导结构的设计，如平板耦合光波导放大器和锥形放大器，也提高了SOA的饱和输出功率。据报道，SOA的最大增益超过21分贝。据报道，最大饱和输出功率超过34.7分贝毫瓦。据报道，最大3分贝增益带宽超过120纳米，最低噪声系数据报道小于4分贝，最低偏振相关增益据报道为0.1分贝。本研究重点关注1550纳米波段高功率SOA主要性能参数的改进和增强，并介绍了1550纳米波段高功率SOA的性能参数、研究进展以及SOA的发展和应用现状。最后，总结了1550纳米波段高功率SOA的发展趋势和前景。
