会议介绍:
论文: 12866-4
标题: S2模式含量测量7+1到1后向泵-信号合成器
文摘: We report a 7+1 to 1 pump-signal combiner designed for backward pumping with higher-order mode content 24 dB lower than the fundamental mode in the output pigtail. 模态含量采用S2测量技术进行测量. The high signal beam quality is attributed to a high-quality taper 和 low overlap splice loss between the tapered fiber bundle 和 the output fiber. The combiner output fiber is large mode area with an LP01 mode effective area of 584 µm2 (MFD 27µm). The large effective area of the output pigtail is ideal for low nonlinearity, high power delivery.

标题: 通过形状传感光纤成像
文摘: Measuring the transmission matrix of a multimode fiber allows for spot scanning at the distal end of the fiber through phase control at the proximal end. We demonstrate a modified shape-sensor fiber appropriate for both shape 传感 和 imaging within the same waveguide. The unification of these technologies opens the possibility of using the reconstructed fiber shape to mathematically update the calibration of the imaging waveguide in a dynamic environment, 正如文献中所提出的那样. Creating a robust method for maintaining knowledge of the fiber’s transmission matrix in an in vivo setting is critical for clinical deployment of this technology.

标题: Determination of a refractive index distribution along a SNAP microresonator from its single spectrum: temperature distribution measurement (Invited 纸)
摘要。我们展示, 理论和实验, that it is possible to determine a nonuniform temperature distribution along a SNAP microresonator from a single measurement of its spectrum. In our experiment, we use a silica microcapillary containing a SNAP microresonator. The microcapillary is filled with water 和 locally heated with a moving heating source (light-pumped microfiber) introducing the temperature distribution parameterized as T(z)=T_0 exp(-|z-z_Q+iw|/L), z是微毛细血管轴上的坐标, z_Q为热源位置, w≪L是震源的宽度. 在每个热源位置z_Q, we restore the parameters of this distribution from the SNAP microresonator spectrum. Our theoretical calculations are in a good agreement with the experimental data.
