摘要： This disclosure relates to polarizing optical fibers and polarization maintaining optical fibers, including active and/or passive implementations. An embodiment includes a polarizing (PZ) optical fiber that includes stress applying parts (SAPs) disposed in a first cladding region, the SAPs comprising a material with a thermal expansion coefficient, αSAP. A core region is at least partially surrounded by cladding features and the SAPs. The core includes glass with a thermal expansion coefficient, αcore. The arrangement of the SAPs satisfies: Rsc=dSAP/Dsc, where Dsc is the SAP center to core center distance, and dSAP is the average SAP diameter, and dα=|αSAP−αcore|, and where Rsc and dα may be sufficiently large to induce stress birefringence into the core and to provide for polarized output. Active fibers in which a portion of the fiber is doped may be implemented for application in fiber lasers, fiber amplifiers, and/or optical pulse compressors.
摘要翻译： 本公开涉及偏振光纤和偏振维持光纤，包括有源和/或无源实现。 一个实施例包括偏振（PZ）光纤，其包括设置在第一包层区域中的应力施加部分（SAP），SAP包括具有热膨胀系数的材料αSAP。 核心区域至少部分地被包层特征和SAP包围。 核心包括具有热膨胀系数αcore的玻璃。 SAP的排列满足：Rsc = dSAP / Dsc，其中Dsc是SAP中心到核心中心距离，dSAP是平均SAP直径，dα= |αSAP-αcore|，其中Rsc和dα可能足够大 以引起应力双折射到芯中并提供偏振输出。 一部分光纤被掺杂的有源光纤可以实现用于光纤激光器，光纤放大器和/或光脉冲压缩机中。
