AN OPTICAL FIBER WITH MORE THAN ONE DOPED REGION AND A METHOD OF SPLICING THE SAME.

摘要

The present invention discloses an optical fiber with more than one doped-regions, the optical fiber provided with at-least one element that substantially prevents diffusion of dopants to and from the doped-regions, during the process of splicing the optical fiber with another optical fiber, resulting in a spliced region, wherein the spliced region between the optical fiber and another optical fiber that exhibits an average value of splicing loss of less than or equal to 0.04dB. In accordance with the present invention the element includes separation between the doped-regions, provision of barrier layers at and around doped-regions to avert diffusion of dopants to and from the doped-regions, creation of barrier layers of high density and provision of a dopant in and around the periphery of the doped regions that nullifies the effect of diffused dopant from the doped-regions. A method of splicing the optical fiber is also provided.
