We propose a novel multi-wavelength fiber optical parametric oscillator (MW-FOPO) based on a ring cavity. A highly nonlinear fiber and a Mach-Zehnder interferometer formed by two 3-dB optical couplers are used as the gain medium and the comb filter, respectively. Multi-wavelength lasing of the MW-FOPO with an ultra-narrow wavelength spacing of about 0.08 nm is achieved. The output spectrum of the MW-FOPO covers a wavelength regime from 1510 nm to 1615 nm (for lasing wavelengths with the power that exceeds -60 dBm). The stability of the MW-FOPO is discussed and experimentally demonstrated. A comparison of the output spectra between the MW-FOPO and the multi-wavelength Erbium-doped fiber laser is also presented.
我们提出了一种基于环形腔的新型多波长光纤光学参量振荡器（MW-FOPO）。一根高非线性光纤和由两个3 dB光耦合器构成的马赫-曾德尔干涉仪分别用作增益介质和梳状滤波器。实现了MW-FOPO的多波长激射，其波长间隔超窄，约为0.08 nm。MW-FOPO的输出光谱覆盖了从1510 nm至1615 nm的波长范围（对于功率超过 -60 dBm的激射波长）。讨论并通过实验证明了MW-FOPO的稳定性。还给出了MW-FOPO与多波长掺铒光纤激光器输出光谱的比较。
