Abstract

In this paper, a semiconductor optical amplifier (SOA) based 1064 nm fiber ring laser with 63.56 dB optical signal-to-noise ratio (OSNR) is demonstrated. The stable performance is measured for six hours with lasing peak variation of ≤±0.115 dB and wavelength variation of ≤±0.006 nm. Combining the fiber ring laser with fiber Bragg gratings (FBGs), the SOA based fiber ring laser is applied to sense stretch, squeeze, and temperature variation. The results show high linearity, which is suitable for interpolation method prediction and evaluation. A large dynamic range of up to 10 km is also demonstrated for remote sensing applications.

摘要

在本文中，展示了一种基于半导体光放大器（SOA）的1064 nm光纤环形激光器，其光信噪比（OSNR）为63.56 dB。测量了六小时的稳定性能，激光峰值变化≤±0.115 dB，波长变化≤±0.006 nm。将基于光纤环形激光器的光纤布拉格光栅（FBG）组合在一起，基于SOA的环形光纤激光器可用于检测拉伸，挤压和温度变化。结果表明线性高，适合插值方法的预测和评估。还展示了高达10 km的大动态范围，可用于遥感应用。
