A widely tunable (30 nm) fiber laser based on a double Sagnac loop mirror configuration is proposed and demonstrated. A semiconductor optical amplifier (SOA) placed between the two loop mirrors acts as the gain medium. The fiber laser has two output ports with adjustable optical power outputs. Wavelength tunability is obtained through the use of a thin film tunable filter, while optical power adjustability is accomplished by proper adjustment of each of the loop mirror reflectivity via a polarization controller. A total output power of + 9 dBm is measured and the potential for higher output powers is discussed. Optical power stability of better than +/- 0.15 dB is measured for 6 hours.
提出并演示了一种基于双萨格纳克环镜配置的宽可调谐（30纳米）光纤激光器。置于两个环镜之间的半导体光放大器（SOA）用作增益介质。该光纤激光器有两个输出端口，光功率输出可调。通过使用薄膜可调谐滤波器实现波长可调谐，而通过偏振控制器适当调整每个环镜的反射率来实现光功率可调。测得的总输出功率为+9分贝毫瓦，并讨论了获得更高输出功率的潜力。在6小时内测得的光功率稳定性优于+/-0.15分贝。
