Abstract

A new tunable fiber ring laser structure employing an Opto-VLSI processor and an erbium-doped fiber amplifier (EDFA) is reported. The Opto-VLSI processor is able to dynamically select and couple a waveband from the gain spectrum of the EDFA into a fiber ring, leading to a narrow-linewidth high-quality tunable laser output. Experimental results demonstrate a tunable fiber laser of linewidth 0.05 nm and centre wavelength tuned over the C-band with a 0.05 nm step. The measured side mode suppression ratio (SMSR) is greater than 35 dB and the laser output power uniformity is better than 0.25 dB. The laser output is very stable at room temperature.

摘要

报道了一种采用光电子超大规模集成电路（Opto-VLSI）处理器和掺铒光纤放大器（EDFA）的新型可调谐光纤环形激光器结构。该Opto-VLSI处理器能够动态地从EDFA的增益谱中选择一个波段并耦合到光纤环中，从而产生窄线宽的高质量可调谐激光输出。实验结果表明，可调谐光纤激光器的线宽为0.05 nm，中心波长在C波段内以0.05 nm的步长进行调谐。测得的边模抑制比（SMSR）大于35 dB，激光输出功率均匀性优于0.25 dB。该激光器在室温下输出非常稳定。
