摘要
本文介绍了一种通过有源区模式控制实现高功率和窄线宽展宽的半导体光放大器(SOA)。通过将模式控制与宽光谱外延材料设计相结合,该器件实现了高增益、高功率和宽带输出。在波长为 1550 nm、环境温度为 20 °C 的条件下,当输入功率为 25 mW 时,输出功率达到 757 mW;当输入功率为 4 mW 时,增益为 21.92 dB。3 dB 增益带宽为 88 nm,输入激光经 SOA 放大后的线宽扩展仅为 1.031 倍。该器件在高增益和高功率之间取得了平衡,为长距离光探测和测距(LiDAR)提供了一种新的放大器选择。
Active Region Mode Control for High-Power, Low-Linewidth Broadened Semiconductor Optical Amplifiers for Light Detection and Ranging.
This paper introduces a semiconductor optical amplifier (SOA) with high power and narrow linewidth broadening achieved through active region mode control. By integrating mode control with broad-spectrum epitaxial material design, the device achieves high gain, high power, and wide band output. At a wavelength of 1550 nm and an ambient temperature of 20 °C, the output power reaches 757 mW when the input power is 25 mW, and the gain is 21.92 dB when the input power is 4 mW. The 3 dB gain bandwidth is 88 nm, and the linewidth expansion of the input laser after amplification through the SOA is only 1.031 times. The device strikes a balance between high gain and high power, offering a new amplifier option for long-range light detection and ranging (LiDAR).
