Title:
偏光及び偏波保持漏洩チャネルファイバ
Document Type and Number:
Japanese Patent JP6657087
Kind Code:
B2
Abstract:
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.
