Abstract
A ribboned polarization-maintaining fiber is used to easily manufacture a polarization-maintaining optical fiber array with multiple fibers and improve the work efficiency and yield. The ribboned polarization-maintaining fiber includes a plurality of polarization-maintaining fibers, and has a ribbon portion of 2 to 300 mm in length surrounding at least some of the polarization-maintaining fibers. The ribboned polarization-maintaining fiber is manufactured by arranging the polarization-maintaining fibers with an exact pitch width while the end face of the polarization-maintaining fibers are rotationally adjusted so as to have a predetermined plane of polarization and then by fixing and coating a part thereof by and with an adhesive, thereby forming the ribbon portion.
