Abstract
The polarization state of a light wave is changed by a fiber polanrzation retardation device constructed by a method including employment of a pair of clamping fixtures, and a series of steps including clamping, cleaving, splicing, releasing, clamping, and cleaving, so as to achieve precise optical fiber lengths to achieve a desired polarization retarding device.
