提出并论证了一种基于多相移取样光纤布拉格光栅(FBG)的半导体光放大环形光纤激光器中激光波长倍增的简单方法。通过改变相移的位置，还证明了在所有双波长范围内波长间隔的可调性。此外，还获得了20多个双波长光纤激光器，3分贝线宽为0.017 nm，信噪比约为45分贝。
A simple technique to multiply the lasing wavelength in a semiconductor optical amplifier (SOA)-based fiber ring laser is proposed and demonstrated, which is based on the utilization of a multiple phase-shifts sampled fiber Bragg grating (FBG). Tunability for the wavelength spacing within all dual-wavelengths has also been demonstrated by changing the positions of phase-shifts. Moreover, more than 20 dual-wavelengths fiber lasers with a 3-dB linewidth of 0.017 nm and signal-to-noise ratio (SNR) of about 45 dB have been obtained.
