摘要
半导体光放大器(SOA)的非均匀加宽特性对产生多波长激光非常有利。本文对两段式立奥萨尼亚克(Lyot-Sagnac)滤波器进行了详细的理论分析,实现了一种基于半导体光放大器的新型多波长光纤激光器。它利用立奥萨尼亚克滤波器的波长选择性,在室温下得到了约18个具有30 dB信噪比的多波长激光输出。波长范围1556~1577 nm。通过调节立奥萨尼亚克环内的偏振控制器,多波长激光的波长间隔可在两种国际电信联盟(ITU)标准波长间隔(0.4 nm和0.8 nm)间选择。这种构型的光纤激光器具有稳定性好、波长间隔可控、信噪比高等优点。
Abstract
The semiconductor optical amplifier has the feature of inhomogeneous broadening, which makes it an ideal gain medium for constructing multiwavelength fiber lasers. A novel multiwavelength fiber laser employing a semiconductor optical amplifier within a fiber ring cavity is proposed on the basis of the theoretical analysis of the Lyot-Saganc filter with two segments of polarization-maintaining fiber (PMF). This fiber laser can generate 18-wavelength laser output with signal-to-noise ratio (SNR) 30 dB and wavelength through the wavelength selection by the Lyot-Saganc filter, ranging from 1556 nm to 1577 nm. The grid spacing of the output laser can be selected between ITU grid spacings, 0.4 nm and 0.8 nm, at room temperature by tuning the polarization controller in the Lyot-Saganc ring. This fiber laser has good tunability and stability with a high signal-to-noise ratio.
