A multi-wavelength tunable fiber laser based on the use of an Opto-VLSI processor in conjunction with different optical amplifiers is proposed and experimentally demonstrated. The Opto-VLSI processor can simultaneously select any part of the gain spectrum from each optical amplifier into its associated fiber ring, leading to a multiport tunable fiber laser source. We experimentally demonstrate a 3-port tunable fiber laser source, where each output wavelength of each port can independently be tuned within the C-band with a wavelength step of about 0.05 nm. Experimental results demonstrate a laser linewidth as narrow as 0.05 nm and an optical side-mode-suppression-ratio (SMSR) of about 35 dB. The demonstrated three fiber lasers have excellent stability at room temperature and output power uniformity less than 0.5 dB over the whole C-band.
提出并通过实验证明了一种基于光电子超大规模集成电路（Opto-VLSI）处理器与不同光放大器结合使用的多波长可调谐光纤激光器。光电子超大规模集成电路处理器可以同时从每个光放大器的增益谱中选择任何部分进入其相关的光纤环，从而产生一个多端口可调谐光纤激光源。我们通过实验证明了一个三端口可调谐光纤激光源，其中每个端口的每个输出波长都可以在C波段内以约0.05nm的波长步长独立调谐。实验结果表明激光线宽窄至0.05nm，光边模抑制比（SMSR）约为35dB。所展示的三个光纤激光器在室温下具有出色的稳定性，并且在整个C波段上输出功率均匀性小于0.5dB。
